Yes, I've already seen it. Sorry, earthlings, but its world debut occurred in Japan today (May 1st, 2007).
The major themes in this installment are miscommunication / misunderstanding and forgiveness (both of self and others). Revenge also helps anchor the storyline.
This is an action-packed film (clocks in at a little over two hours) that doesn't waste any time getting started. Lots of twists and surprises, as usual, with both Tobey Maguire and James Franco showing a bit of range in portraying the good-guy/sinister-guy personalities that reside within them.
There's a lot of digital imagery in Spider-man 3 (special effects), but for some reason I didn't mind it as much as I did while watching the Matrix trilogy. On the plus side, the plot isn't too hard to follow. The villains (everyone seems to take a turn being one in this flick!) help keep the audience guessing, so my overall reaction to this movie is positive.
Spider-man 3 hits theaters in America on May 4th.
