This was rather poor, but I admit I was kind of excited to see a Hulk/Iron Man pairing, so perhaps my expectations were too high. To break it down
– Good: a few (a very few) of the shots and action sequences were quite good. I liked seeing the Hulk wearing a little Iron Man armour.
– Bad: Quite shallow, childish script that really made this not suitable entertainment for anyone over, say, 13, but at the same time it seemed a little strong and full on for younger kids. The CG mostly looked very poor.
– Odd: A section where the guys had to fight off monsters that seemed to have nothing whatever to do with the main story. Yeah, watching the duo fight a pack of wendigos was cool, but made no narrative sense at all.
