Seriously, SH 5 is so much fun. I love the targeting for guns, it's so much better than in the previous games. Plus you can tuck and roll to dodge, and that in and of itself is a wonderful ability.
If you ever get the chance to rent it, I totally recommend it. It's challenging enough to keep you actively engaged, and the puzzles aren't stupidly easy either. I hate that, I need my games to make me think! But yes, I think you'd enjoy it. It gets very Hostel-ish in the last levels so that's always fun.
