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.
Ha, this will only further infuriate those people who bitched mightily about the implied locations of the statue and the Black Rock. How DID the ship end up so far inland?? Awesome map. Don't forget John, some locations (Lighthouse, the Heart)
