Ratchet & Clank is probably my only possible answer here, and even that might have more to do with my tastes changing rather than the games growing on me. I didn't really care about the games as a kid, because I wasn't a fan of the shooting part, and it felt kinda clumsy as well. However, as an adult, I didn't really have any trouble pushing through the first game despite its clumsiness (in fact, I think I had a good time), and it's only got better from there.
I'm tempted to try Halo again some time because it's often so cheap, but I've already given the original either two or three good tries, and it hasn't been fun even for a moment. It's a series I'm actually interested in getting familiar with, but I don't think it's just ever going to click with me.
