It was actually kinda strange with the Spider-Man 2 posters though...
Again, I felt they were "overdone", but I really liked the individual titles, "Destiny", "Choice", yaadi-yaadi-yaa... (some might've found them corny)
Those also helped in linking the posters together in some way.
But I felt the Alex Ross paintings in the titles were far better than any posters. Had he painted the posters as well, that would've been amazing.
Of course, it wouldn't have helped so much in marketing the film... but then I guess the masses like "cool" posters as opposed to something more natural.
