Cdelplato:
In order to break in your new home theater right, I heartily recommend "Terminator 2: Judgement Day", starring Arnold Schwarzenegger. This is a "sci-fi" film to be sure. But if it's special effects and action that you crave, then there is nothing else out there like "Terminator 2". If "Terminator 2" turns out to be too supernatural for the wifey, then I would recommend something else like "Lethel Weapon I". This movie has a lot of action in it, but no "supernatural" effects are in this movie. If she loves Mel Gibson (and I cannot find a woman who doesn't), then maybe this movie is more her speed. But do, try "Terminator 2: Judgement Day" first and see what you think. That also was MY first DVD (and I have about 60 now) too, by the way. Other movies that can challenge your new home theater system also include those like "Top Gun", "The Matrix", "Independence Day", and "The Specialist".
By the way, congratulations on your new home theater system. By buying a new home theater system yourself, what you did now was join a sacred fraternity. Once you experience home theater, believe me (and I'm talking from experience), you will NEVER go out to see a movie EVER again.
Again....... Congrats........
