The TOS movies were made to reignite a series that had been canceled after 3 seasons, expanded on worldbuilding and characterization. They made sense.
The TNG movies were really just quick cash-ins on popularity...and frankly, none of them matched up to All Good Things.
They did feel like cast reunion parties where they sometimes forgot to invite the audience in for the fun, though was "fun" the intent of the TNG movies? Q had promised worldbuilding at the end of TNG's "All Good Things..." episode... The only movie that comes close to Q's promise is "Generations"... yet it feels lacking, to the point I even almost prefer the discarded/original version of Kirk's death because it's using tragedy instead. But that only involves the coda of a character, is "The Nexus" as grand and mindboggling as Q alleged? (Not really, the Nexus has more to do with Guinan's people (and the Borg) being well within 23rd century space, leading to more questions instead of the intent to answer them, among other problems.)
All that doesn't mean the other TNG films don't have moments but they don't have the same feel and scale the TOS films had. Then again, "Turnabout Intruder" didn't promise there would be any future adventures either...
