Bigger stack should have raised the flop. The turn call is pretty bad, especially because the Q is a horrible card for him because some of the time bigstack should have a KJT9/KJ98/KQJT type hand (often w/ spades) that now steals some of biggerstacks outs. In biggerstacks mind, most of the time bigstack pots this turn it should be with a set, a wrap or at worst aces with some kind of backup like the spades. Bigstack should never have gotten to this large turn pot with unimproved aces, so biggerstack is really lucky that all his outs were clean.

This shows the danger of overplaying AA out of position. You get to the turn with a big pot and it seems like you have to fire the second barrel because the pot is so big.

That said, I actually like this turn bet from the AA once he sticks himself here, because the flop pot size was big enough for biggerstack to jam a set and the Q misses all the draws. AA is still ahead a pretty good percentage of the time and needs to get folds from hands with outs or get his value now from biggish draws, because there aren't really any safe river cards and there's no way for him to get his opponent to make a mistake on the river.

In general, as someone else pointed out, a lot of the dynamic in this hand depends on how certain biggerstack is that bigstack has AA.
