Nope, the most over-rated film in history would most definitely be The Matrix. Hands down. IMHO, of course.

T2 was really just a rehash of the first film. Good guy and bad guy from the future duking it out to save/destroy a certain target. I really enjoy both the first and the second film. I think the second film is ranked as high as it is by so many people is because it managed to be more fun in the way it did it. The first film was very dark, the second film was much more light hearted (though it was still quite grim), I think in this way it simply appealed to a wider audience. I agree the first film works perfectly by itself, but I enjoy the second one too much to write it off.
