Just got the dvd today and watched this episode. I had an ancient VHS of this so the dvd version was a vast improvement. No 5,000 particles of dust on the t.v. screen... a clear picture. Oh the technology makes my head hurt. I watched the cgi edited version...apart from the lazer blasts they really did not do too much cgi. The story may not be the best dalek story but it still holds up today. Very enjoyable.
