Seriously.. I rewatched this the other day and I found it faaaaar funnier then most of the popular funny movies like anchor man or superbad or whatever the fuck.
Jim is a little over the top in it, but not too much like ace ventura, he sells it here, his facial expressions make this movie. The whole "Medieval Times" restaurant scene was perfect, especially when they were fighting with the battle axes and Jim was making the star trek sounds, I had to rewatch that part half a hundred times. The "Sam Sweet" mini story with Ben Stiller was brilliant. "I think it was an Asian gang or something... There was this guy, he looked Asian... and he was speaking another language, I'm pretty sure it was... Asian." LOLOLOLOLOLOL. Love the fucking plot, it's rather dark actually and has more depth then it appears to.
Really, I have no idea why most people consider this a terrible, unfunny movie. I have seen this said time and time again. It was fucking hilarious, ahead of it's time, and left me wanting to rewatch it instantly. That rewatch recently just probably put it in my top 20 funniest movies ever list.
