The easiest way for you to get a handle on these episodes is to see one. They are in weekly syndication right now if you live in the United States. Check
here to see which station locally is broadcasting them. Don't trust the times shown on the list; check your local schedule instead. Be forewarned that six minutes or so will be cut out for syndication. The remastered DVDs are complete.
Anti_Drone and
AC84 have been leading discussions in this forum on the broadcasts.
Another way you can judge the remastering is to look at the
HD screen caps over on Trekcore. They've posted about half the first season episodes so far.
Otherwise, this is a good time to sit back and enjoy your current DVDs. Only season one of the remastered DVDs has been released and that was on HD DVD, which as you probably know is a dead format. There are regular DVD versions on the flip side of those DVDs, but still, they are $100 on sale and seasons 2 and 3 will never be released on HD DVD. Unless you already own a HD DVD player, I'd recommend waiting for the hi-def Blu-ray versions instead.
As for the effects themselves, it depends on the viewer and the episode. Many purists on this board decry them from the get-go, feeling Paramount is trashing fond memories of theirs. Others find the CGI Enterprise to be cartoonish. While I sometimes felt that way when watching the syndicated episodes, once I had them at home and saw them in hi-def, I no longer believed that. For some reason, in HD, the cartoonish effects go away to me.
Once you accept the remastering, it then depends on the episode. Some, like
The Galileo Seven, benefit greatly by the remastering in my book, giving that episode a sense of place that was initially lacking. Others, like
The Corbomite Maneuver and
Space Seed, just look stunning to me and I thoroughly enjoy the remastering. And then there is the occasional episode like
Metamorphosis, where I feel the remastered effects are simply bad and, to me, detract. This fortunately doesn't happen too often.
BTW, the sound track is identical to what you have now.
I hope this helps.
