How much you like this depends on whether you watch the show. I've only seen the very first movie and a few sporadic episodes. I found them enjoyable because of the banter, and that's why I watched this movie when it came on Amazon Prime for free. It's a typical bad guy travels through time and changes history in his favor when on the verge of total defeat; heroes have to reestablish the time line in which they win.
The banter of the show is here, but much of it falls flat because I don't know enough. There's a lot of other "inside" jokes that pass me right by, although I can sort of guess I should be laughing or winking or something. The result is that it moves too slow for me.
As far as the overall quality of the movie, it has TV production values. Not bad TV production values, but still typical TV values. Script is passable. Many scenes not really believable but who cares if you like the characters? A pass unless you love show; in which case, it's probably 5 star.
