I'm willing to go along with a 'giant crocodile that gets thawed out and terrorizes the sea' - it's sci-fi. I can even go along with the ill-conceived plan to re-freeze said croc (thereby making it the problem of the future) instead of killing it now. But what will happen to the croc you're trying to 'save' when you tranquilize her underwater and drag her underwater for a long distance? Last time I checked crocs breathe air, not water. I'm fairly sure that a tranq'd croc can't hold its breath... Congratulations geniuses, you just killed it. Steve Irwin is rolling over in his watery grave. Not one of the better episodes.
