I have entirely the opposite viewpoint. I felt the second game wasn't as good as the first, simply because there were too many gosh-darned orcs to keep track of. The first game you had a nice number of them, and if the Nemesis system did its job properly there would be one or two that you absolutely grew to loathe--I remember one in my first playthrough who killed me at least four times, obviously getting more powerful and harder to kill each time. That didn't happen second time through, which is a shame.

Shadow of War? Gave up on it. Not only were the stealth elements conspicuously diminished in favour of the whole "war" thing--and I really liked the stealthy bits in the first game--but, as mentioned above, I didn't really get to "know" any of the orcs and never got that sense of personal hate.
