Favorite "So bad it's good" movie?
That could be almost half of my movie collection, honestly. The whole "so bad it's good" category in general is quite subjective, and much like with my music, I'm quite eclectic of what kind of films I love despite the lack of critical acclaim or positive reviews they may have had, or whether they have a cult following or not. More often than not I tend to like films that many others don't, or understand and acknowledge that they're not good but don't care either way because I found something enjoyable about them despite that.
That being said, I think my most favorite from my collection is probably the Resident Evil franchise, because while they don't follow the video games at all and aren't remotely scary, the films are still incredibly entertaining action-packed where Milla kicks major ass, and that is all I'm looking for, to be honest. My second favorite would have to be Book Of Shadows: Blair Witch 2, because I was obsessed with it when it came out and even if it seems completely nonsensical it was still entertaining and, considering the theories surrounding The Blair Witch some of the events that happened made sense in a strange way. Following that would be any teen or slasher movie from the 90s/early 00s, because I basically live for those.
(I wanted to say things like Spice World and Josie and the Pussycats or some J-Horror splatter films like The Machine Girl or Tokyo Gore Police, but those were intentionally created to be outrageously ridiculous thus awesome so I didn't know if they counted or not; regardless though, I loved them as well and they're definitely among my favorites.)
