I do think they are overrated, but still good. I've never thought of the series as divisive, though. Seems that most people who play them at least think they are decent. The first and second game have pretty terrible third acts involving cheesy mystical BS. The third one lacks that (it sort of teases it, but turns out it is something of a drug trip). That makes the third one far and away my favorite. So it's actually getting better with time.
