I dunno, I mean, I like the show, and this episode was certainly good.
For a Valentine's day episode, it wasn't awful for me, like so many things relating to it are. People get rejected, everything isn't sappy sappy, and things in general just go wrong for people (Don't think I'm a fan of that sort of Drama, as much as how that sort of thing feels more real to me, like how Blaine and Kurt didn't actually get together at the end of the episode). I guess there's just something that my cynical side just can't get past:
They're in high school.
Admittedly, when you are in high school, relationships always feel real and more important than anything else, like they could turn into something real and long lasting, but they don't. I'm not saying it doesn't happen, but it's very rare for that sort of thing to last long in the real world.
But the show is treating it like it's a serious drama, and like they're going to get married or something. I'd love to see an episode where the characters realize the futility of attempting to find love in a high school environment, or something like that. Of course, that would probably ruin the show.
I do definitely feel more invested in Mr. Shue's relationships, and his problems, because they feel real and possible, the consequences feeling long lasting.
That being said, I still watch the show, and it's still enjoyable to me. I'm just super cynical.
