Yes. However, in some other scenes, you see Reno still knows how to fight. And he always had some idiotic traits...think about the Wutai scene when he rebuffs Elena, saying something like "Just looking at you is making me sober".
Anyway, I'd have been happy with a less goofy Reno, too. What strikes me much more than that is that in the game he wasn't all that pretty at all, he had a thin, angled face with high cheekbones, and now they've almost made him into a bishounen.
