Is anyone else playing this?

I've completed Trainee/Easy and am about halfway through Agent/Normal level. A number of reviews have dinged the game for 'spotty gunplay,' but not really gone into specifics. Any observations/opinions on this? From my own experience, it's a non-issue - your aim point is the center of the screen. I'm more annoyed at the assumptions about damage/range of particular weapons - there's a scene where you have to shoot a gas can on the back of an armored vehicle; two or three shots from a pistol works fine, half a clip from a machinegun doesn't do diddly.
