(spoiler extended) why Maekar is considered a bad king?

Yes of course baelor's death is big elephant in the room but beside that. Why?

From the list of rulers on the iron throne he seems rather... normal? bro was genuily dutiful and did his job for seven years and try to stabilize a realm that goes from conflict to conflicts that weren't started by him

I know the jokes about the Maekar/stannis comparison but Jesus christ Maekar is a depressing sad character man..
