Perhaps "Dumb People" was too strong of a term, because the film itself was not particularly unintelligent. What bothered me about it was the poor storytelling methods they used to get from plot point A to plot point B. There were several cases where it felt as if they couldn't figure out how to logically move from A to B, so instead they just said, "Bam! We're already there!"
Also, every time Chekov spoke, I wanted to take a power drill to my left temple.
