I went with the kids to see it, and was pleasantly suprised. While it wasn't Airplane/Top Secret/Naked Gun funny, it was surely Scary Movie funny, and damn sure better than Epic Movie or The Comebacks...probably not saying much though. My kids really like Drake Bell (Drake and Josh), and he was funny, as was Leslie Neilson and Shooter McGavin (I'll remember his name later). It was a pretty straight takeoff on Spiderman with some random X-Men (Tracey Morgan as the Professor) thrown in for no real reason. A very sophmoric sense of humor is required, as there are plenty of crotch-shots and fart/booger jokes, and it's chock full o' silliness for good measure.
This site http://tvlinks.voodeedoo.org/ has a mother load of great cartoons and TV shows with most of them containing entire seasons. Enjoy them while you can as I am sure they will soon suffer a You Tube type demise.
