Transformers.
Yeah, indeed, I admit. What can I say? The macho-man deep inside me loves all the explosions, and the nerd inside me loves watching giant robots duke it out, even though it's hard to follow. I haven't seen Revenge of the Fallen though, and I doubt I'd mind it as much as most people apparently do.
And also the Star Wars prequels. The Phantom Menace is actually my favourite. I really don't mind midi-chlorians (just a Force sensitivity indicator people, nothing more), Jar-Jar was annoying but not that bad and least it didn't have Emo-Anakin. It did have Liam Neeson, Darth Maul and a friggin' awesome podrace.
