Would have preferred more Captain Marvel in the fight.
Without things getting cheesey I would have preferred more Captain Marvel to be honest.
It really does make the character seem shoehorned in when you consider the usage vs buildup for CM.
They could have had her destroy the ship, then had Thanos get the gauntlet and give her some one-liner about him being the victor - only for her to taunt his ego and say he could take the easy way out and span her away - or he could fight her and prove he is worthy while she buys Cap/Tony time to regroup and get the stones off him, and still have it end the same way.
Maybe that would have been cheesey anyway.
