a great movie but id only recomend seeing it if you have watched (and understand) the first 3, or atlest get the first 3 on dvd and wtach them before you go see it, if you dont you'll be completely lost and think its the biggets load of shit ever.
lots of people (and reviews i read) said it was really confusing and too many twists, but if you just remember the characters and things that happened in the previous 3 it unfolds very well
