It's an uneven Steven Spielberg film. The car factory scene, with Tom Cruise in the end escaping in a brand new car is a fun sequence and Spielberg at his best. At the same time, it seems he's afraid that the film is too dark, so he puts in some groaninducing attempts at humour. To give the film a noir look, the colours have been bleached, and it works sometimes, but looks really ugly other places, like in the hothouse scene. And he can't help but give the film a happy ending, where actually, Cruise locked up, dreaming about his lost son, would have been the perfect way to end it.
A 70s parody of 50s Westerns, it's slightly dated, the comedy is sometimes a bit too broad, but it's still a fun film. I wish I had seen it when I was twelve. I'm sure I would have found it hilarious and my mind would have been blown away by the ending. It's rather Monty Python and The Holy Grail, at age twenty, that had that honor.
