I can't add anything new to the fine professional reviews that are available so I won't try.
For those of you who hated the film, I suggest that you get a dictionary and look up the word 'review.' I'm amazed at the number of numbnuts commentaries. Perhaps you should read some of the professional reviews and try and learn something from them, like, what it was you weren't understanding about the film. Really though, don't bother. I know it can be a strain to use your brain too often. As one person commented, Spiderman 4 will arrive and until then you can hang out at TGIF and listen to Jessica Simpson.
