I picked up the Transformers Movie 20th anniversary DVD. I have an older DVD of the movie and one time when I worked for a web design company, about 6 years ago we would have movie day once a month where we would have pizza and a movie. We watched Transformers The Movie on movie day and everyone loved it. It is a fun movie and also a tough movie to watch because they kill off Optimus Prime. That was tough to take as a kid, Optimus was the best Autobot, why did they have to go and kill him off? It was a sad time.
The 20th Anniversary DVD has many great extras in it. It is worth picking up to refresh your Transformers knowledge before the live action movie comes out in 201 days.
