Very briefly: I really liked it, even in spite of that terribly overdone part in the middle (which wasn't nearly as terrible as the 'Spiderman without his powers section in part II). At the very least, it is way more entertaining than the borefest that was Spiderman II.
I, for one, do not understand the backlash against this movie from critics. But then they loved part II, and I can barely sit through it.
Anyway, it gets my endorsement, for what it's worth.
