The only two major weak points I can think of in BB are the S2 plane crash and Tuco's cousins. Mainly because both were given a lot of build up and were ultimately anticlimactic. Otherwise, nitpicking about specific lines or "slapstick" moments seems silly. Breaking Bad is unapologetic about its absurdity; it has always had a layer of dark humor from the very first episode and the very premise is arguably unrealistic. To me, stuff like that just doesn't detract from the show, because the dialogue, characterization, atmosphere, and storytelling is strong across the board.
i think the plane crash is weak, but not because it was anticlimactic. i thought the very premise of it crossed a line of what i'm willing to suspend my disbelief for; they were trying to pin that on Walter, and it just seemed really forced and absurd.
Walter opened the door which disturbed Jane and caused her to roll over and then she started to choke on her own vomit and Walter didn't save her and then her dad discovers her and is distraught and his sadness means he does poorly at his job and him doing poorly at his job causes the planes to crash. this show has had its fair share of borderline absurdity but i mean, really? the writers seemed to forget about it midway through the third season at least.
