Oh Look, Rocks!

Most of this serial's actual story happens in its final episode and that final episode still feels slow, what happened to Terry Nation between the masterpiece that is Android Invasion and this? Like I'll defend Planet of the Daleks and Death To The Daleks to my last breath (they're bangers I'll hear nothing to the contrary) but this...
Davros sits in silence making no resistance or noise while being captured, he's wobbling all over the show when he moves and the Daleks are nearly falling apart more than usual. The core concept could be interesting except it just never is, why is Davros just like... chilling there? I figured the Daleks would be resurrecting him but nah he's fine he was just REALLY sleepy I guess, needed a centuries nap?

The whole experience just feels flat and unsatisfying, absolutely my least favourite of Nation's serials, and possibly Dalek story in general so far (at least Asylum is entertaining)
