I think it's mostly still TOS fans who tend to look down on the newer series as never quite living up to the original. We are of course right to do so.
Several of the scripts were adapted from the aborted Star Trek II TV series, which was going to have most of the original crew return. Spock being the notable exception.
Happy if JJ never gets near a Trek set again, but as far as the new series are concerned, I'd rank them all between "pretty good" and "excellent". Except Picard, but even that mess was at least a better send off than Nemesis.
Berman? Best thing he ever did was stay away from DS9, and that just because he was too busy making Voyager worse.
This looks and reads like it is from a grocery store gossip rag. Look, I'm sure fans were upset, but I'm old enough to recall the hype for TNG and people were excited AF generally.
Difference with every Star Trek that came before and what we have now:
Every first season of Star Trek after TOS was pretty bad. When you have just the first season of a Trek series to go off on then the reaction to something mediocre is pretty normal.
Season 1 TNG had... problems.
Season 1 DS9 is boring as fuck.
But these series got better and earned the respect of the fans with later seasons.
NuTrek has had 17 or so seasons across 5 series and it's STILL trash! The current executives have chosen quantity over quality and don't give a damn about improving anything.
