Sliders Plot Holes

In Season 1 Episode 1, the sliders land on a planet  that has gone through an ecological disaster, possibly nuclear winter. They start out in Quinns basement and proceed to find and light candles to see and warm their way through the house as they try to make sense of the antarctic-like climate in San Francisco. The professor was also seen using a lighter. They walk out the front door of Quinn's house to find Rembrandt and his cadillac. They all sit inside the cadillac until a tornado comes their way. Quinn opens up a wormhole before the timer was ready and they slid to the next world.

What doesn't make sense: Why didn't they just take cover in Quinn's basement and wait on the timer for the next slide? It's common knowledge that basements are the safest place to be in a tornado. They also had the supplies to build a fire so they could've kept warm and had shelter from the harsh winds.

Plot Hole: Quinn had to help lift Wade, Rembrandt, and Professor Arturo for them to make it into the worm hole because it was high above Rembrandt's cadillac. How was Quinn able to make it through the worm hole with no help? He was standing on the car so he would have been unable to get a running start, and their was no one to lift him up as he did  for the others. Not to mention the snow and ice that had accumulated on the car would have made it slick.

In Season 4 Episode 8 "The Alternateville Horror", the sliders land on a world where the Chandler Hotel appears to be haunted. In actuality people are not seeing supernatural events, but rather people who are stuck on the astral plane. One of those people is Matthew, the young son of the hotel owner who only Colin can see. The others are doubles of Quinn, Rembrandt, and Maggie who are moving objects in the hotel in order to get people's attention.

Plot Hole: If Matthew and the doubles can move solid objects such as doors and chairs, then why are they unable to touch people (also solid matter)? Also, why isn't the hotel owner angry at the scientist who caused her son to disappear? Also, it is unclear whether the doubles and Matthew are able to eat food on the astral plane. If not, then it seems as though Matthew could have starved to death while stuck on the astral plane because it is implied that he disappeared a long time ago.

How I Met Your Mother Plot Holes

In Season 1, Episode 2 "Purple Giraffe", Ted throws a party in hopes of seeing Robin again. Robin fails to show up and calls Ted to apologize and ask if he's throwing another party, so Ted throws another party the next night which Robin misses yet again. Robin apologizes again for missing another party due to work. Ted then throws a third party, and just when it seems like Robin no showed again she appears.

What doesn't make sense: If Ted wanted to see Robin again, why didn't he just call her and ask her out again? Obviously, Robin was into Ted to a degree otherwise she wouldn't have kept calling him every time she missed his parties to apologize and ask if he's throwing another party.

Also, why didn't Robin just send Ted a text message letting him know she wasn't going to make it?

At one point, Robin is doing a news report from a store where a kid had climbed into a claw machine trying to get a purple giraffe.

What doesn't make sense: Clearly, the child was around 3-4 years old and so large it's impossible that he could actually fit inside a claw machine. 

Big Bad Beetleborgs Plot Holes

In Season 1 Episode 1, Jo, Roland, and Drew enter a haunted house off a dare from a couple of rich snobs. In the house, they come across various ghouls such as a skeleton and a Frankstein knock off. They also encounter Flabber, a phantasm who was released from some sort of exile inside of a pipe organ when the kids bumped it while trying to find their way out of the house.

What doesn't make sense: the kids can't seem to make up their mind whether they are afraid of these ghouls or if they are annoyed by them. One minute they are screaming and running from the ghouls, and the next minute they are like "Ugh, I'm tired of this". Also, why did Roland faint upon seeing Flabber the phantasm, but didn't faint when seeing the skeleton or the Frankenstein knock off? At the point that the kids found Flabber, they were actually lost and couldn't find their way out of the house. When Flabber gave them a wish, why didn't they wish their way out of the house? Another thing is it was never explained how or why Flabber got trapped in the pipe organ to begin with.

Humorous note: Did anyone else notice that Flabber looks like a cross between Jay Leno and the joker from Batman, but acts like a poor man's version of the Genie from Disney's Aladdin?

V.R. Troopers Plot Holes

In Season 1 Episode 1, Ryan and Kaitlyn are with J.B. as he is on his computer. Suddenly, the computer stops working. J.B. claims his computer is dead when all of a sudden a strange guy appears on the computer screen claiming to be Professor Horatio Hart. Professor Hart tells Ryan to come to his laboratory because he knows his father. In the next scene, suddenly Ryan, Kaitlyn, and J.B. are in some desert looking area and come upon a triangular structure which they feel must be a portal of some kind. A voice comes out of nowhere and tells them to enter the portal.

Plot Hole #1: Ryan, Kaitlyn, and J.B. find the laboratory without Professor Horatio Hart telling them where it is. They just suddenly were at the laboratory.

Plot Hole # 2: After the kids make it to the laboratory and put on the visors Ryan sees an image of his dad. J.B. says it's just a playback (a pre-recorded message), yet Ryan is able to talk to his dad and interact with his dad's virtual image by touching hands with his dad's virtual image. How could he talk to and interact with his dad's virtual image if it was just a playback as J.B. claimed?

What doesn't make sense: The kids just blindly listen to some guy that hacked into their computer simply because he says he knows one of their dads. Then they blindly enter the portal because some voice told them to. Then they put on some mysterious visors because some guy they just met 15 minutes ago says it's ok.

Pokemon Plot Holes

General Plot Holes: In Pokemon, trainers are taught to take care of the Pokemon they catch and to love them. The plot hole in this is that by fighting pokemon in order to become "Pokemon masters" they are actually engaging in animal abuse for the sole purpose of notoriety. To make matters worse, trainers force their pokemon to live in tiny balls (called pokeballs) where many go unused and stuck inside those pokeballs for long periods of time which would seem to be neglect.

Season 1 Episode 10 "Bulbasaur and the Hidden Village": Team Rocket (Jessi, James, and Meowth) get caught in a net. Since Meowth is a cat, why didn't he just chew through the net or claw the net open?
