There are been many times where I wanted to just turn my XB off and never play this game again because of something stupid happening like lag or shooting someone only having that person turn around and kill me, but like most people I svcked it up and kept playing.
Eventually there will be a patch(s) that will clear up some of the bugs you people are bringing forth, until then either leave Crysis if in your opinion it is "that bad" or continue playing and enjoying the game.
The problem is that you people make it seem like there are so many glitches/bugs/exploits that it is impossible to enjoy the game which is absolutely untrue, you probably just svck at the game and go negative most rounds. The more you play then the more these little glitches wont bother you.
