I actually like TOS-R. While I grew up watching the original versions, I think the remastering project came up with some beautiful animation, made the series feel a lot more real, and fixed a lot of mistakes (the inconsistent engine design, the recycling of the Botany Bay for the Woeden in "The Ultimate Computer," etc.).
My only two complaints are that the IKS Gro'th was inconsistent with the design in "Trials and Tribble-ations" (DS9) and I do miss the original Tholian ship in "The Tholan Web" (although I respect the decision to create more consistency with ENT).
P.S.: About "The Doomsday Machine": As I understand it, the CGI planet killer was re-designed to invoke the episode's author's original intent (that it was loaded with weapons, an idea which was revisited in the TNG novel Vendetta). So, the CGI planet killer was designed to look like it had been battle-scarred, had the secondary weapons the author had wanted torn off, and that it had been weathered in it's journey across the void. So, there was some thought to it. In fact, if you look at some of the articles on Memory Alpha, there was actually a lot of thought given to some of the changes made.
