About slowmo in movies, I admit that I like it when it's used well. I really liked the Matrix 1-2, and Sherlock Holmes 1-2.
The thing that really irritates me is close ups and lots of cuts during fights. You can't see anything. If however they show the fight, using some slowmo to emphasize parts is fine by me, it's kinda cool sometimes.
The thing about a well choreographed scene is that it's really a lot of work to pull it off. Slowmo or not, when you see lots of cuts, it's usually because they are cutting costs.
