Short answer? Yes.
TNG's "sophistication" (for lack of a better term) was just too heavy for the cinematic world. TPTB were force to reinvent the series to be like the swashbuckling adventure TOS was and it just didn't work. I've often said that most of TNG's action scenes (or at least FC, INS, NEM) literally looked like grown men in the backyard playing astronauts and aliens with their ray-gun toys. It was just too hard to take seriously, which is why I think GEN, even with all its problems, is the best of the lot.
Somethings have no business on the big screen. Because you can do a thing doesn't mean you should do a thing. Or something. I'm sure that, throughout TV history, there have been countless series where someone said "Let's make a movie!" and everyone else in the room facepalmed. TNG should have been one such series.
And your point about Berman is also a good one. I tend to defend him more than most and think he is capable of many good things. Film making is not one of them. Paramount should have insisted on bringing in new talent. And when I say "talent" I actually mean talent and not names to drop.
This sounds about right to me.
Plus, I think TOS had a greater range, enabling TOS to make a variety of movies. TOS can do action, comedy, drama, melodrama, adventure, high concept sci-fi, and so on.
I don't think TNG had that range, and by that point TNG was being reduced to space action films every time anyway.
It's too bad, because I think a TNG movie like "The Measure of a Man" would have been refreshing and great. But the movies require super-villain evil bad guy and kewl space battles and fisticuff actions. Oh well.
