So you're keeping ST:V then?
As for the animated series (TAS) it's entertaining & rather good considering that it was a early 70s kids cartoon. He-Man recycled parts of it which is why it may remind you of something else. TAS's noted for having quite a few good Trek or science fiction authors for writers. D. C. Fontana, David Gerrold, Larry Niven, Samuel A. Peeples, even Walter Koenig.
Alan Dean Foster adapted the epiodes in book form as
Star Trek Logs. You can find the 10 volume version books cheap if you just want reading copies. There are usually two versions of each cover, I prefer the one with cel images from the show. Why? Because they flesh out the episodes and don't limit your visual imagination like TV can.
In short, TAS really feels like a continuation of TOS with a different format and budget. It's not as groundbreaking or challenging as the best of TOS but it's very entertaining.
Sidenotes:
Some of the early Trek novels and non-fiction books are rather good if sometimes period oddball. World of Trek I & II (?) even had some short stories by cast members and back then so little was developed yet some rather fun now abandoned or written over tangents were taken.
I wouldn't mind a similar show for Star Trek like the latest Clone Wars series, but then I'm a heretic in this thread.

Hope this helps and as always Your Mileage May Vary.
