Twilight (no explanation needed), Lord of the Rings (I don't really hate it as such, but it's just never interested me in the slightest), pretty much every Disney movie (some of them actually scared me when I was little, the others are boring sappy crap), Juno (it was boring and the dialogue was often plain stupid, homedoodle), every single romcom (the plots are all identical and, like the Disney films, they're sappy crap), and Star Wars (for the same reason as Lord of the Rings).
There's probably more but those are all I can remember right now.
