Meatballs wasn't a B-movie. Did you hear about the Polish terrorist that tried to blow up a car?
The sequels were, and a lot of sequels are B-Movies. Like Dream a Little Dream 2. Watch Dream a Little Dream, that's compatible with someone liking Zapped!
Zapped wasn't a B-Movie either.
But yeah, this is totally my thing. I love 80s B-movies. 80s B-Movies are easy to spot, because they went straight to VHS after a failed run at a tiny number of theaters. Where big budget movies that were bad, simply were run when the seasonal line-ups were weak. Some straight to VHS movies weren't B-movies, of course, as all a B-Movie really consists of, is being an Arthouse picture, opposed to a studio picture.
Trancers. I've suggested this movie like 200 times on the forum. LOL. One of my all-time favorites. My absolute favorite low-budget movie of all-time. It's corny, takes itself way more seriously than it should, and has a fun and crazy plot.
Class of 1984 - If you like Meatballs and Zapped, this is also good.
If you liked Zapped, then there are a lot of made for TV movies that were actually pretty awful but good. That's another place to look. There are just so many suggestions, and simply throwing them out there is really useless. Mainly because the arthouse and obscure genres of films also include a lot of skin comedies, gore, skin horror, and just a see-what-will-stick attitude towards sci-fi.
