The fishes were quite rude to Marlin

What strikes me with this movie is frankly how unfriendly most of the fishes are. Practically majority of the characters strictly refuses to help Marlin to find Nemo and some of them are downright rude to him. With the exception of Dory and the pelicans, Marlin is unfortunate enough to just encounter fishes that are mostly rude or dangerous (with the exception of the fishes who turns into different characters, but they were only persuaded by Dory). I felt genuinely sorry for Marlin, having practically few who were willing to help him.
