I’m with Warbler on this one. First Contact was good the last time I saw it (ages ago), but would surely not hold up now that I’m more familiar with the TV series.
First Contact was the only TNG film I liked when I saw it in the theatre (having seen all the TNG films in the theatre). But it really just has so many serious problems that don’t fit with the series. For one thing, because they need to fix the Phoenix and convince Cochrane to fly it, they basically throw temporal and cultural non-interference completely out the window.
