What about Brian is unlikeable except for the fact that you prefer Ian because he was the first guy introduced?
He's unlikable simply by having the flashback too long, you don't have to think too deeply. To be honest, I don't like the story that much to care about any of the characters but knowing about Ian's dislike about being a reincarnation of Brian definitely play into that too
Usually, I don't mind flashback but isn't this flashback too long? It's almost like they're making Brian unlikable by just making the arc too long to end
