I'm a big fan of offbeat, improv-style comedy shows. See what I thought of some recent outings.Human Giant"The television incarnation of Human Giant came with its own built-in cred and a cult following of indie tastemakers already familiar with the comedians’ work.The best thing MTV could do to cultivate this fan base was stay out of the show’s way, and for the most part, it did."Acceptable TV"In the wake of Internet monsters like YouTube and MySpace, VH1’s Acceptable TV has come up with a trendy gimmick: it’s interactive. This premise sounds innovative and exciting in theory. In reality, the show is… acceptable."Stella: Season One"Stella—not a sketch comedy, not a sitcom, and certainly not the Marx Brothers—forges a brand of television comedy all its own."
