I don't mind all the spiderman movies.. But you don't at many stages feel like you're watching a 'great' 'blockbuster' movie... Kind of like the new 'batman begins' movie. The writers of that batman remake did a lot better job at adding depth and a dark personality to the whole film...
I think they really needed to get that right in the first spiderman, but didn't,, and haven't been able to slide that depth or personality anywhere in the last 2 either...

They are still fun to watch, but with the storyline they had to work with and the technology available, they're was always the opportunity there to really nail the series...

That being said though, I think they are still great fun to watch, and I can certainly think of worse movies...
