An excellent summer blockbuster - the general feel of the film is identical to the first two, which when coupled with the original cast returning, really makes it feel like chapter three instead of just another sequel. The old themes return - duality, good versus evil, choices, responsibility and relationships. The thing I always really loved about the Spider-Man movies is the characters, and they, again, are the main focus here.
The only thing which stops this one from surpassing the previous entries is that there is a little too much going on in it. It's not that the movie isn't long enough, it's that Sam Raimi seems to have divided up the screen time rather bizarrly - Venom gets around about the same amount of screen time as Mary-Jane's singing, which doesn't seem right.
In summary though, a few minor problems aside, Spider-Man returns and doesn't let the fans down. Watch and enjoy!
