Spider-Man: FoF should be credited for what it does do right, and that's kid-friendly fun.
The reason my tagline was kid-friendly fun is because that's all it is. I picked up this game for gamerscore, but found it surprisingly fun. It offered easy to pick-up and play combat, a fair amount of variety as far as moves go, and the option for a second player to join in at any time. Add in upgradeable moves and memorable bosses from the comics/movies/etc. and you have a 6-7 hour game. If you crunch the game in a small amount of time, you'll find it very repetitious. That's why I recommend playing a world or so each day so you don't get too bored of it.
The real downer is the enemy variety. Your enemies are Phantoms. You have small, medium, and large Phantoms; all of which are easy to defeat. Occasionally you might confront a Phantom with an actual life-bar, who I just avoid all his moves and kill him just as easy. And lastly you have your bosses, who are each different in their own way and simple to understand.
So to cover the same base one more time, it's a simple, easy, kid-friendly game that you CAN play alongside with a child. Whenever you die, it's also very rewarding. All you lose is a bit of coin (the same coin used for upgrading called Tech Tokens), and it's a very very small amount. Add in the fact that every level of every world is pretty much the same, and someone as young as 6 years old can play this competently. That's all I really CAN say, it has nothing else going for it.
The graphics and sound is okay, nothing spectacular. The replay value is nil, offering nothing except a versus mode. And the achievements challenge you only to your patience of dealing with repeating the same activity over and over.
I recommend a rent if you don't have a kid, and a possible buy if you do have one. What it DOES do with the Spider-Man universe it does well enough not to hurt the reputation, but not amazingly well to make this game more memorable than a one-night stand.
