^ While I do see the point you're making, I do also think that TAS has led to a lot in Trek fandom getting concerned about any animated foray into the franchise. In other words, there is definitely a contingent within the fandom whose sole experience with Star Trek in animated form "burnt their fingers", so to speak, and so they are therefore understandably reluctant to see the franchise ever try that particular medium again.
There are many people who won't be able to see that Trek could work very well in animation, until such time as somebody actually does and proves the point.
With all due respect, nobody is really going to care about an animated series except die hards who visit sites like this...I think that TNG's return (with some younger cast members) from a commercial point of view is a no brainier.
Star Trek: The Animated Series was made 40 years ago, by a company (Filmation) well known for recycling animation footage as much as possible.
If Trek fans are stupid enough to let something made that long ago blind them to the potential of a new animated series...I don't know what to say!
And, done right, I don't think a new Trek cartoon show would be limited to just existing Trek fans. In fact, I suspect a lot of existing Trek fans might snobbily dismiss it in any case.
No, I think a new animated show could find a younger generation of fans. Of course, it would be a bit more action-orientated (and I know some fans wail and gnash teeth when they see that phrase) but that doesn't mean it still can't have all the other elements we know and love about Trek.
Let's look at it this way: Trek fans often seem to hold up TAS as a reason why animated Trek "won't work". But... well, The Clones Wars has been moderately successful, and the fact that Star Wars had it's fair share of cheesy cartoons in the 1980s didn't do anything to harm that success.
