Too many villains in general. Comparative to the likes of TASM 2, to be honest. Lockdown was fantastic though. And I'd love to see more Autobots die onscreen.
Oh my god, he was handled fantastically in those shows; Animated especially. And let's not exaggerate about Galvy in TF5, though he has the possibility of dying in a dumb way.
In fairness, at least he had to be jumped by all the Autobots and NEST to be taken down in addition to being blinded.
