The one thing that bothered me
First off I love Lethal Weapon 4; it's my favorite after the first one (maybe even with 2). And I think that final showdown is one of the best in the action genre. I loved it except....for when Rigs gets trapped under water.
First off, I hate anything that has to do with drowning, because I know just how indescribably agonizing it is to not be able to breath. But they made him be down there for way too long! I mean Rigs didn't even have time to take a preparatory big gulp of air before the thing collapsed and pinned him down under water. And they made Rog take forever to come to and figure out what happened. And then when he finally does, when he's all, "Ah, ah hear you Rigs! Ah hear you!", and taking off his clothes, I'm like, 'you could have jumped in ten seconds ago!' I'm just thinking, way too much time! And then, when Rog is down there with him about to help lift the thing off him, Rigs (who should have been just writhing in pain) decides to give a three count. I'm like yeah right; you know how much time has passed already? And you're just calmly giving a three count?
I don't know, I mean it was a very tense scene and really has you on the edge of your seat. I just wish they had made it a little more realistic and not had Rigs down there for that long.
