Cecily and I went to see Iron Man 2 at The Family Drive In Theatre in Stephens City, Virginia (not necessarily relevant, but I thought I would mention). Actually, the film was paired with How To Train Your Dragon (film) — very good pair. Anyway, I wanted to jot a few notes/give a small review (and this should be fairly brief).
Overall it was a fair to good movie — certain it would have been just as good as the first had it actually been the first. That being said, in my opinion it went a little over the top with the cheese/tongue-in-cheek/comic book cliche. The biggest example to me is the pepper spray scene. While funny, the timing was very awkward and it really kind of cheapened the scene.
Best line of the movie? (paraphrased) “Excuse me I’m fighting off a Hammer-Roid attack.” 
That is good stuff!
Also another major high point? Scarlett Johansson in tight leather (a la Uma Thurman — The Avengers) and a very hot hairdo.
So while the movie didn’t wow me, it was actually very good, just familiar and so it didn’t excite me, but it’s certainly worth seeing, and I would definitely see it again.
And the icing of the experience was when our two-year-old son woke up at the end of the movie (when AC/DC was playing over the credits) and very sleepily headbanged and rocked out. 
[SPOILER!]
Oh and if anyone else wondered what they found in the teaser at the end of the credits, apparently it was the Hammer of Thor.
