It was so poorly done because, by that point, Sasuke had been gone from his team for as long as (if not longer than) he was actually with them. And in the brief time he was with them, they didn't get along due in large part to him treating both of them poorly. The only "bonding experiences" they had were in life threatening situations where they had to work together to survive. So you have Naruto and Sakura basically dedicating their lives to finding some guy they barely knew a few years ago, and then they do find him and he almost kills them just to get them to leave him alone, but that doesn't deter them? What even was their plan at that point? Were they going to just kidnap him and hold him until he agreed to... live in Konoha again? Be part of their "team" again? I have so many questions, lol.
