They have mission goals which were achieved (booster was caught). Goals that they didn't think they could do (Starship being within the buoys). While there was flames and those could be dangerous you judge the mission based on the planned outcomes but they will try to eliminate the anomalies to improve the next mission while still achieving the goals.
The thing is that no one is judging the mission based on this imperfection. It's just intellectual curiosity, which is a good thing. The comments that are getting down voted are all assuming some negative motive that just isn't present.
