Interesting list, which garnered a pretty decent list of recommendations.
Iron Man = quite fun. Have only watched the first one.
Aliens as mentioned but realize that Aliens 3 is a good movie, just not all that good as an alien movie.
Live Free or Die Hard, some pretty amazing action, of course. A little bone headed on the attack the infrastructure front. However, Oliphant does have a moment when he sees the chaos that he and his hacker buddies wanted to happen. And Bruce’s daughter is a hoot.
