I liked IM3 and the story line was semi predictable but also a few surprises, it was a good action movie for me, comes down to personal taste at the end of a day.

I haven't seen Tom's movie yet, I also like an eye candy thinking movie as well, though Tom does seem to be a very arrogant actor which comes through his screen characters, where in IM3 Downey wasn't as arrogant compared to IM 1 & 2 which was a good thing.
