That 70s Show is one of the funniest TV shows. Period. It is well cast, well written, well acted, well done.
Unfortunately, a show like this means that I don't have much to write. I can't really think of anything bad about it. The characters are all funny, and the plots are always hilarious. All of the actors involved bring their characters to life in the funniest ways, from Rhet's "dumbass" comments to Kitty's nervous laughter.
The accuracy of the show historically is pretty high. There are constant visual and verbal references that make you believe that its the 70s, from the gas shortage to the legal drinking age. The drug factor is pretty high, as it was back then (hell, it still is...). In a good amount of the episodes, there is a scene where the 4 male friends are sitting around a table, obviously high as a kite, and the camera keeps shifting from one to the other, getting each of their reactions to the conversation. Those are some of the funniest episodes, IMHO.
Well, I'm gonna cut this review off now, since I'm running out of things to say. If I say more good stuff about the show, I'll sound like I work for Fox. Here's the review, short-and-sweet style: It kicks ass.
