OK, let's get the gripes out of the way first. YES, the Daleks are seen to wobble, YES there are times when McCoy's delivery could have done with a little tighter direction in places, YES the time controller is a plasma ball (but hey they were new at the time, how was it their fault if the Gadget Shop then bought loads?)and YES there are appaling continuity errors (most notably the 1980's block of flats in clear view, when the Headmaster dies, in what is supposed to be in 1963).
Right, now that's done on with the praise. Remembrance of the Daleks has what the last Dalek stories didn't; a really, really good script. After Genesis of the Daleks, the stories were essentially about Davros, NOT the Daleks, here they come to the fore and are allowed to be more menacing than they had been in years. The two factions of Daleks slugging it out at the climax (especially the Special Weapons Dalek-where is he in the new series?!), them going up the stairs, and a clever use of the Emperor all bring them to a new high.
The script is incredibly complex, you watch and see racism, fascism, ethnic clensing, use of children as soldiers, teenage crushes, dealing with mistakes from the past all rush through. The Doctor, though condeming the Daleks for their genocidal ways, essentially deals the same to them, and these are the first seeds of what would become McCoy's REAL performances later to come (watch him in the undertaker's. Superb). This is where the (sadly) deleted scenes come in to their own, they do add SO much more to the telling.
The cast is excellent too. The late Dursley Linden, Simon Williams, George Sewell, Pamela Salem and Michael Sheard all give their parts the seriousness they deserve, lifing it from the 'pantomime' criticisms of the late period, and the little girl is chilling! Sophie Alrdred's performance brings the series back to track companion wise. The only thing I have trouble with is Terry Malloy as Davros, a good attempt, but no Michael Wisher.
