These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
YMMV: Weird Science
The TV show:
Creator's Pet: Chett. The producers liked Lee Tergesen's Large Ham performances so much that they started writing bigger and bigger parts for Chett, eventually making him a Secret Keeper in the final season.
Growing the Beard: Starting in the second 13-episode season (when Wyatt's hairstyle changes) the writing improved considerably, moving away from the premise of the movie toward more fanciful magic and sci-fi adventures, and giving Chett more to do than just be the Butt Monkey.
In "You'll Never Eat Brains in This Town Again," while trying to coordinate a stunt, Chett kicks a zombie's head off - except he thought it was just a student actor and subsequently thinks he killed someone. While trying to bribe Wyatt into not testifying against him, a panicked Chett exclaims, "I can't go to prison!" Turns out, he did go to prison.
In the second episode, Wyatt and Gary get a hold of a universal remote that allows them to control time. Sounds familiar.
