I must admit that this feedback does not disagree with Daniel Kelly's review of Galaxy Quest, however his statement that "The world should hate Tim Allen" is jarring. Especially when Mr. Kelly provides no evidence for his opinion. He describes Allen as "irksome", but goes no further.
Tim Allen is a guy's comedian whose success is that he taps in to "guy" things without stooping to shock profanity or ethnic stereotyping. Anybody who has ever tried to get their car to go faster than stock, or traipsed off to Sears for a Craftsman Tool fix can identify with his humor. Sure, he can get a little gross at times (he coined the term "Vurps" for vomit-burps), but his heart is in the right place.
He was at his best during his TV series Home Improvement. In a time when TV shows were all about agonistic family relationships, here was a guy who would do stupid things, cause the disaster of the week, but deep down he cared about his family. My favorite episode was when he taught his oldest son to use a cutting torch while working on the hot rod. That brought me back to my childhood with my Dad, patiently teaching me about what was under the hood, and starting me on a life of car enthusiasm.
So don't dismiss Tim Allen out of hand, he has provided a lot of enjoyment to a lot of people over the years.
