I wouldn't know if it's the best Spiderman game as theultimatebulk said, but that's only because this is the only Spiderman game I've played. I will say it is a good game, not great , but good. It is short, as far as story mode goes, but you can go on from there to complete the challenge courses, which can be tedious, but fun. A downside to the game is the overall LACK of Venom playability. I was all ecstatic when I heard you could play as him, but disappointed when I saw how little you actually played with him.
If your in it just for the story mode, rent it. If you want to complete the entire game, unlock all the different costumes, and all that, then buy it.
And in regards to the first post, sorry, no tips. It took me FOREVER to catch up with Electro. It was such an evil level... ;_; All I can say is to keep at it, and when he stops, remember to stay back a bit or you'll be blasted away by that stupid super shocker move of his. Grrrrrrrrrr! *recalls the mann failed attempts at beating that level..*
