This was always a single movie, they just released it in two parts. But while the first part went quickly over the events that set up the arrival of the aliens and presented the main characters, thus compressing a lot of the original manga/anime story, this part loses the pace and gets to have a few boring scenes. They are mostly flashbacks and emotional explanations of what the characters felt (even if it was quite obvious from their actions and they were dying :) ), but still, a little jarring. I think a better edit of the material would have created a nice two hours and a half single movie that didn't suffer from pacing issues.
That being said, the movie ends well, with too little of Gotou, one of the more interesting characters in the story, but with great development for all the others. Maybe except Satomi Murano, who was always the damsel in distress and not doing very much. I recommend this movie to sci fi fans from all over. While the philosophical speeches increase in number in this part, I still think Parasyte is a good sci-fi horror movie that needs more recognition.
