... by the sheer evident crappiness of this movie.
Seriously, I refused to watch Avatar with family, boyfriend, or friends because I knew I would hate it, but just watching that sample scene, the big blue character designs were so off putting, the background colors so garish, the dialogue about "This not to be thanked for! This is sad!" was so clunky and grating that I couldn't finish it. I cannot imagine watching a double feature length movie of that kind of thing, Riffing be damned.
Any movies you won't watch, even with RT?
