I didn't think the wrench thing was fun at all. Nothing can kill you. 300 slicers in a row will all die miserable deaths. I watched my friend wrench the final boss with no problem in horror.
Actually, even playing through as I did - with a mix of weapons and plasmids - isn't that great. Even though the graphics are amazing, the environments are very 'samey'. Each area looks different, but you'll pretty much find the usual: a few slicers, maybe a big daddy, some weapons, some circus of value, maybe a safe etc etc. Its really all the same area repeated. The saving grace is the story, which has some really cool moments (excluding the awful ending)

The worst disappointment is the balance of the game. Its broken. I won't say exactly how, but its possible to play through the entire game killing virtually everyone with your wrench. This with no plasmid purchases either. Thats just terrible playtesting for a game this big.
