Trollhunters: Rise of the Titans

I think Trollhunters is the best series there is. I've been a fan for years, and I don't like the ending of the movie because it ruins the whole story. The movie itself was quite decent, except that Trollhunter Jim's amulet didn't work from the beginning, which was a bit silly. But there are so many logic gaps. For example, why was Toby suddenly not wearing his armor when he was riding in the taco truck? Why is the first episode completely different after the time is turned back? The alarm goes off at 8:00 AM and not 6:00 AM. Toby climbed the rope, but that wasn't the worst part. Why does Jim decide to give Toby the amulet when he can't even jump without getting out of breath? And nobody knows what happened to Clarie, whether they got back together or not. I also don't understand why there were so many unnecessary deaths. Strickler dies at the Titan because of the bomb, but Jim actually went on that mission, so how can he die? Why didn't Nomira wait until nightfall, and why didn't Duxie just leave the original seals where they were? But there were also good parts, like in Hong Kong where they have the mission in Troll Market, or where they fight against the law in New York. I think they should either explain things to the fans or make a sequel.
