Plot hole: The 'real' villain needs Vic to investigate the drop and be there, so he'd be killed in an incriminating spot. Problem is, the boss also throws in a deadly ambush by a whole gang early in the day; if they killed Vic, Vic would have not been where the boss needed him to be. Even more absurd is the fact that the boss is also aware in advance that Vic is having Lasik that day, making it the worst day ever to pick for such a scheme. There was basically no chance Vic could pull off the investigation in that state, and even in the unlikely (it does happen in the movie!) case that he'd manage to show up blind as a bat at the drug deal and get killed as intended, nobody investigating would ever believe that someone with a major drug deal on his hands would have gone through eye surgery the same day.
Continuity mistake: Vic threatens Stu with giving him "zero stars"; Batista is pointing the phone at him and the tip of the index is at the top of the phone. Reverse shot, and he's holding the phone with all the fingers together at the side.
Continuity mistake: The back, side window of the car gets smashed, but is back in one piece in later shots.
