Instruct: Classify Amazon reviews into positive or negative sentiment
Query: Struggling to finish

This is another sci-fi book that I bought because the Amazon reviews were excellent.Unfortunately, I am 200 pages into it after 2-3 months of working on it. It just doesn't beg me to pick it up the way some books do. It's sitting on the edge of my desk right now piled under 2-weeks of bills and junkmail. It's only on my desk because my wife brought it in from the kitchen when she was picking up.I feel obligated to finish it and figure out what's going on, but it's almost like chinese water torture. There's so much stuff in it that doesn't contribute to the story and, after 200 pages, I don't feel like it's progressing towards a conclusion.The biggest problem I have with books like these is the excessive technobabble and jumping back and forth between timelines, ships, locations, and even characters. So at this point, I don't even know who the main character is, or if there is a main character.
