plastic beach arc was cool and i loved hearing from murdoc so much but i dont like how they chose to just make him more and more cruel after that. like he wasnt entirely awful to begin with, just bad in a cartoony way. his cruelty in the plastic beach arc was taking it up a notch and you could have figured that it was due to the rejection from the band breaking up and losing noodle, and his isolation later on, because he rebuilt noodle and had 2D around for company occasionally and the last pirate radio ended on a happy note with them getting along via making music. it seems like theres a lot to go from there.
but then in phase 4 they had interviews where murdoc is abusive in a nasty grounded way, and suddenly 2D became oblivious to how bad it was. except for when they had the voice actors portray them, then they just acted like an old married couple. never consistent.
i hope they figure out what they want to do with their characterization this time. seems like they want to do something narrative based.
