The Transformers: The Movie

Well, I agree that the appeal of this movie is mostly to fans, but I was never a big fan of the series, and I loved it. It's definitely not mainstream, but for anyone who can appreciate robots voiced by some big names (even Orson Welles!) thrashing each other with a very cool, hugely 80s soundtrack, this is where it's at. The main plot, although not exactly inspired, is at least compelling. Any of the scenes with Unicron (Welles) or Galvatron (Leonard Nimoy) easily make the movie worth watching, and there are a few scenes that actually have heart. If you don't like 80s cartoon action, stay away. But if you'll always be a Megaman-playing, Ninja-Turtle-watching kid at heart, check it out.
