Belle & Sebastian: The Adventure Continues

I don't know if they made a trilogy out of one book or they totally made the sequel up. Because this is so out of the story when you think about the prequel. Where's Guillaume now? He disappeared like Pierre's mechanic disappeared at the end of this movie? Where's the German soldier from the previous movie? Why do the characters disappear? It's not only about the friendship of a boy and his dog. The storyline should also be consistent. The characters shouldn't disappear into the thin air. Guillaume and the soldier were courting angelina already, there was no need to add pierre into the list of her lovers. That's too much. Also, i should mention that sebastien told Gabriel that he'd never had a girl "friend" before, like, was it someone else that befriended the jewish girl in the first movie? Such inconsistencies make me question if i should watch the final chapter... Because this one barely deserves the 4 stars i give.
