The TNG movie formula did not serve PS well. And the odd thing is he kept pushing for things that I feel were not in his best interest! More action/dune buggy/physical stuff, instead of insisting on crafting more intelligent scripts.
This is along the same lines as Shatner writing and directing ST V. He comes across better in II, III and IV than he does in his own piece!
TNG could have pulled off plots closer to Syriana and Mission Impossible, and less of Die Hard and Aliens.
