Let it never be said that I do not give credit where credit is due. I have complained on more than one occasion that Glee has failed to create characters and storylines that I care about, that for me, on a weekly basis, the show lives and dies by the songs that are sung. If the songs aren't ones that I like, I find the episode disappointing, if they're ones I enjoy, I'm really happy with what we've been given.
I'd now like to add an addendum to that idea.
There is in fact a character on the show that I really do care about, a character who I think needs way more screen time, is well-written, beautifully acted, and perhaps the best part of the show. The unfortunate thing is, this character isn't one of the stars nor one of the regulars, he is merely a recurring part of the series. The character in question is none other than Burt Hummel (portrayed by Mike O'Malley).
In a television series which is full of over-the-top performances and an incredible amount of foolishness (I'm not knocking that stuff, but let's be clear about what Glee is), Burt represents a breath of fresh air and a rare three-dimensional, real person. Quite possibly, he's the only such figure on the show (although Kurt isn't far off).
Let's look at Burt for a moment – here's a guy, whether he's right or wrong, who has this view of reality, of the world, and then realizes that his son doesn't fit into that view. Burt doesn't try to change his son, molding Kurt into something that works into Burt's view of how things are. No, Burt does something which is personally much more difficult – Burt does his best to change who he himself is; to accept a new point of view—one which doesn't in any way match his own experiences—and find a way to still connect with Kurt. Burt doesn't always succeed, but in a show which is full of absentee parents or ones that don't seem to get or to care to try to get their kids, Burt repeatedly goes out of his way and well out of his comfort zone to be close to his son.
