5. Spider-Man 3 (2007)
The culmination of a plot point we'd been waiting to see explode all over the screen since Sam Raimi gave us the first installment in his Spider-Man franchise - that of Peter Parker and Harry Osborn's crumbling friendship - should have made for a truly awesome showdown, which is what I imagine everybody expected to see come
Spider-Man 3. Alas, what we got was a movie that was so jam-packed with plot threads that it was hard to care. Who'd have thought? It's become relatively tired to explain what was wrong with
Spider-Man 3, so I'll skip it. And although I've defended the movie on a number occassions, given that I don't think it's quite the abomination that the rest of the world seems to, I can't argue that its sardine tin-like structure, which seems to both waste and meander interesting story points whilst remaining horribly bloated at the same time, makes this movie dull as heck.
