While it isn't saying much, First Contact was the best TNG movie; of course, TNG movies are consistently mediocre. The movies I consider the best are from the first 6 as are the movies I consider the worst. The TNG and reboots are firmly in the middle.
Anyways I think the failing of some of the Star trek films is they are trying to be another Wrath of Khan.
Into Darkness ticked all the boxes, as did Nemesis, but neither did it with a decently motivated villian we actually cared about seeing gone. First Contact also went much the same direction, but at least that had some interesting dynamic and the Borg actually fit as an antagonist to revisit with Picard's Conflict (though, they did kind of both that).
I just hope this new movie isn't just Search for Spock Mk II given they are blowing up the Enterprise.
