Got to be jaws for me.
Doublenaw, close encounters brah, all about them aliens.
Not even a close call. Raiders. Still among the top 5 action movies ever made. Crusade is a fairly distant second.
E.T. is worth seeing. Once. Before age 12.

Yeah, I'm sure 99% of us have fond childhood memories of that one. And it is a great, escapist movie for kids. Probably my favorite movie as a kid. That inevitably introduces some bias. I recently saw someone who reviewed Ghostbusters, seeing it for the first time as an adult, and reviewed it very favorably, but that's another one that I can never be totally sure about.
