Too easy, too short, not worth playing, but if you really want to, rent it, beat the game, return it.
Good
Graphics on the characters and enemies are pretty good. The game is kind of like inbetween 2-D and 3-D.
Making enemies like Venom and Doc Oc on your side is pretty fun, especially when you get to play as them.
Bad
The game is waaaaaayyyyyy to easy. The thing is, the enemies look different in harder levels, but they are still as easy to kill as enemies in the first level. Also what makes it easy, is that you never actually die. Like when you start levels, you pick who you want to be your partner to fight the enemies. (Some examples are Green Goblin, Venom Rhino and Doc Oc, depending on where you are in the game.) SO when you die, you get to control your partner, so basically you just jump around until your other character comes back to life, which takes about 8 seconds. So it is nearly impossible to die.
Another downside, is your partner when controlled by CPU, is useless, they hardly do anything. Of course the game is way to easy, so they don't need to do anything, but still.
Also, the game is way too short. There are like what, 20 levels. The whole game for me took about 4 hours. On average, I think it would take about 7 hours to finish the game.
The power ups and mini games are extremely easy to buy. You need to collect coins in the levels to buy stuff and upgrades in the heli-carrier(the base of operations basically) And even though the stuff are as much as like 5,000, they are still easy to get because you can find coins everywhere, and I mean EVERYWHERE!

Good

Bad
-Way to easy
-Way to short

-Upgrades and stuff are too easy to get(which in a way is kinda good)
