While some of the elements that make The Naked Gun: ICUP unique and interesting also get in the way at times, it's still a worthwhile adventure. And while the jokes (like the game itself) can be hit-or-miss, when they hit they're an absolute riot.
I.C.U.P.'s sharp, cartoonishly exaggerated visual style looks good, but that's not nearly enough to save it. Without the bugs, this would be at the low-end of franchise cash-in mediocrity; with them, it's just plain bad.
There are very few games like this on the App store, which makes it worth playing if you care even a little bit about the adventure genre. It'll make for a nice breath of fresh air between all those physics puzzlers out there.
