A shameless Back to the Future copy that doesn't even try to hide it - and somehow that's both the film's biggest problem and its only real charm. The 70s production design is genuinely fun to look at. But the writing is lazy, the comedy mostly falls flat, and the time travel logic is brushed aside whenever it becomes inconvenient. It's the kind of film you watch on a lazy Sunday afternoon, don't think too hard about, mildly enjoy, and forget by evening.
