The TOS movies seemed like labors of love. The TNG movies seemed like cashing in on a brand name.
I don’t have specific examples on hand, but I do believe Patrick Stewart had a lot more clout and creative control in the TNG movies. Stewart seems like he’s got an ego, and doesn’t care about the integrity or legacy of Picard as a character beyond being a vehicle for Stewart to either do the acting he wants, regardless of its appropriateness to TNG, or as an excuse to drive dune buggies around for fun.
