Actually I dig seeing him in the show. Having a actor playing a complete tool-yet-useful is refreshing. It's like the guy is free to "disturb" the established CW recipe for soap. And the enthusiasm of H.R. is, in the end, a strengh. I find it also shows Tom Cavanagh real talent in this season, he's more natural than most of the cast, exception of Jesse L. Martin. I mean, in the end, there is a show, outthere, where there is a "useless" character ! That's quite refreshing.
