It was an okay movie. It's just that it was too fast paced and they could have made it 1/2 an hour to an hour longer. Also there were storylines that did absolutely nothing for the plot (like Steve being pregnant and the wedding that was cancelled 5 seconds after it was mentioned). Didn't like Jim's new VA (this on I can forgive because you guys probably couldn't get the original VA so you had to settle for the next best thing). I hated how Toby did absolutely nothing until the end and died like he was one of the most important characters in the movie, he did so much in the original show and they turned him into a comic relief (and not even a good one). Then the whole thing of Jim time traveling to make Toby the trollhunter instead of him.
TLDR: the movie was okay, would have been better if they had just stretched it out into another series instead of condensing it into another movie.
