If it's crap ... We'll tell you
I need a Cadbury creme egg.
One I can think of right now:
I can see why some would think not, but I would speculate he actually gotten worse from when we saw him in TOS. He started off as this competent and intelligent world leader who controlled a significant area of the Earth, having a prize that even Alexander the Great didn't have. However, he loses this empire and his followers, fleeing into space with his people. He didn't lose his mind however during this journey, he was aggressive, but he wasn't obsessive about revenge when he took over Kirk's ship, he just wanted to gain power again. Again he lost and was exiled to watch his followers slowly die off including his beloved wife. During all of this his mind just obsesses over getting revenge on Kirk and as we soon see in the movie, that obsession overrides his logical thinking that we saw before. Some he went from the logical and competent ruler of an empire of millions to dying, alone, on a broken ship, in a nebula in what was then the barren end of Federation Space all because he was so obsessed over revenge.
Any adaptation of The Yellow Wallpaper. I think there's been a couple.
