I just found it clunky at that point. They were going for these cinematic/filmic/dramatic/cool moments, but the engine felt unresponsive at that point. However, that mission where you have to run through the town that's being bombarded, and making it through unscathed gets you 100%? That was awesome. It's just a bit too hit and miss for me. I'm keen to see what AC4 does to streamline or refine the gameplay.
