Now, on some TV shows and films, old effects have been remade either for a re-release of the series on television, or else release on DVD. Of various TV shows, I can name the original series of Star Trek, Doctor Who, and Red Dwarf.
Opinions, if anyone has seen films/TV series with new enhancements? Should they be optional, like with Doctor Who, able to be available either as an option, or else part of a special edition? Or do they need to be built in, like the remastered versions of Star Trek or Red Dwarf?
Personally, I feel that some of the CGI effects added to some of the DVD releases of Doctor Who work well. Not all of them (they do enhance, but don't actually impress or add that much). I did like the work done for the release of Kinda (the CGI Mara is probably the single most impressive work of CGI I have ever seen), Earthshock (the scenes involving the freighter crashing into prehistoric Earth is one of the better enhancements ever done, giving more impact to that final scene), The Invisible Enemy, The Invasion of Time, as well as the special editions for The Curse of Fenric and The Five Doctors.
CGI enhancement, I feel, should be optional.
I've lived for over 2000 years, and not all of them were good ones. I've made many mistakes. And it's about time I did something about that.
