If you guessed it, yeah, I did not like this series. The problem with Monster was that the overall series was just plain boring. The story would drag on for far too long, and sometimes the story of take a detour from the main story-line to focus on character development on a supporting character, it does it often. There is some exciting moments, but not enough to prolong interest for the series.
Then there are the characters. I did not get into any of the characters, most of them were just regular people that were thrown into a situation that they are unfit for. There wasn't much any likable quality to them.
