Great special effects and costumes. Wonder fun to watch.
Also, a nice continuation of the storyline. We learn more about Hellboy's past, more about Liz's present, and get a nice look into Abe. Relationships aren't easy, if you're in one or want one, and there's a lot going on between the monster bashing.
I'm not a real comic fan, nor do I know anything about the Iron Man universe, but this movie makes me wonder about what I've been missing!
This was a great introduction to the IM universe because we get to see the complete process of Stark becoming Iron Man. Part of the charm was the step-by-step process not only of Stark's character development, but also of how the suit comes together a bit at a time.
There were so many good laughs, jokes, and even slapstick scenes that help lighten up the darker parts. Robert Downey Jr. was just fantastic in this movie, and just steals the show from the special effects. Wonderful supporting cast helped make this a very enjoyable movie, which is why I've already seen it twice.
