AND THAT'S THE THING! Too many charaacters, they're all 2-D and it's frustrating, I feel like I can't connect with them at all, especially the queer characters.
Well, first off, I do have to agree that Glee is not that great at telling stories with as large of a cast as they have. There really is a lot left to be desired there. However, having many characters doesn't necessarily mean that those characters can't all be interesting, relatable, and fully fleshed out. (Take Game of Thrones for example.) Where Glee's problem comes in, however, is that they try to focus on their core characters (Finn and Rachel) while simultaneously trying to develop their other characters. Unfortunately, there's not enough time to do both, which leaves the audience having to fill in quite a few blanks.
However, that's not what you were complaining about. You were complaining specifically about the queer characters, so let's not get too side tracked from that point.
You say that you feel like you can't connect with the queer characters, but that doesn't necessarily make them 2-D characters. In fact, the queer characters have been some of the most 3-D characters that we've seen on the show. (Santana and Kurt especially. Blaine has a lot of promise and they've started fleshing out his character a few times, but Glee has failed to completely follow through with a lot of it.)
People throw around the words 2-D and 3-D characters, but there's not really a concrete definition for those terms, so they don't mean much. However, Santana and Kurt have both had some good backstory. They've both had a lot of struggles and have changed significantly over the course of their stories. They both have faults. They both have quirks. They both have drive. (Blaine has all of those things as well, though he has not had as much time spent developing those characteristics as Santana and Kurt. Brittany has faults and quirks, but not much else, and I would agree that she is more of a flat character used primarily for comedic relief.) What more do you demand from your 3-D characters? And does anyone actually measure up?
Not everyone is going to be able to relate to every character, but that doesn't make that person a bad character. For example, I can't relate to Puck, Quinn, Mercedes, Finn, Sue, or Artie 99.9% of the time. Does that mean those characters are flat? No. It just means that I haven't been through that kind of stuff. On the other hand, I relate very strongly to Blaine, Mike, and sometimes Rachel.
It just seems like you're defining 3-D character as someone you like and 2-D character as someone you don't. I could be wrong though. If you'd like to tell me what you mean with those terms, that would change things.
There's nothing wrong with you not being able to relate to certain characters, but does that also mean you can't empathize with them or enjoy their stories? (If the answer is no, that's fine. I'm just trying to understand where you're coming from here.)
