The thing is some of these movies are going for that whole "so bad its good" type silliness so does that mean they were really bad, or that they are actually GOOD at targeting their audience? The better ones imo aren't the ones that are intentionally silly, but the ones that take themselves seriously and end up being terribly funny. Thats why I am going to have to go with something like "Showgirls" because its hillarious and it takes itself dead serious too . Also on Starship Troopers I love that movie and actually think its not even that bad viewing it in a serious manor, but when you add in the stupidity it makes it soo much better, probably one of my favorite movies that I know is terrible but I just can't stop loving it .
I would also so go back and watch some older like 80s action movies, there are a TON I used to love and going back you realise just how god awful the plot (and often movie as a whole) is, but they are still great. I'll nominate Red Sonya as a winner in that category along with the Conan movies (which are somewhat better). I used to love those movies as a kid, but from any sort of plot perspective they are so corny and over the top its funny .
This also leads me to my next statement: IMDB and Rotten Tomatoes are stuck way to far up their own asses, don't go trusting their reviews and stuff and thinking if a movie isn't on the IMDB Top250 that its not gonna be good, those sort of websites only like ONE type of movies and if its not your taste in movies then you will be soorly disapointed. I know I started watching alot of their Top250 movies and thinking "well shit there really must not be all that many good movies out there if this is all we got", but thats bull crap, there are tons of great movies that don't all get the same recognition but are just as entertaining. Also, just because you find movies like "Stalker" and "Citizen Kane" to not be entertaning at all doesn't mean your somehow less intelegent than the movie snobs, just that you have a different taste that doesn't happen to include boring movies that are stuck up their own asses (if I want that I read Ayn Rand novels ).
