I rewatch movies ALL THE TIME, especially during Christmas and Halloween. There are a couple of other films that I put on consistently as a comfort watch (The Guest, Dread, etc.). I have watched entirely though all 3 Stargate Series at least 3 times each. My wife and I often rewatch Psych and The office. I have watched through all of the Star Trek series at least 4 times each. I am on my 5th or 6th time through Futurama. I have watched Fringe twice at least. Twice through X-Files. I don't know how many times I have watched Firefly. My wife has been through Friends at least 5 times. And she has watched Murder She Wrote (the entire series) probably 30 times. I have watched Columbo in its entirely no less than 3 times.
