I just caught up after missing four episodes, including the most recent one so here are my thoughts on each character.
Rachel
I'll start with her since she's basically the main character. So... I'm liking her a lot more this time around. She seems to be getting caught up in all this drama. Now, this whole thing with Jesse and Finn. Its getting out of control. Finn obviously likes her, so just break up and avoid the Prom fights, thank you very much! On the good side, she also has had some great solos "Jar of Hearts" was fantastic! Though I like the original better, she sang that so effortlessly. And her duet with Jesse on "Rolling In The Deep" was great. She's having a good round of solos
Finn
Yeah, I hate Finn and probably always will. Why is he dating Quinn, when everyone knows he likes Rachel? And Rachel likes him back too! We haven't heard from him in awhile too. I'm sorta glad since I personally think before I was wrong about the Rachel solos, but the Rachel and Finn duets. She sings better with other guys. So, so far, he is a bump of the log and I don't like him at all!
Quinn
To finish off the love triangle, I go to Quinn. Quinn was my favorite from my first episode and I've been not liking her lately, but after the Lucy Caboosey story, it was great to hear how damaged she really is. You now truly understand her. I also loved her duet with Rachel "I Feel Pretty/Unpretty" just fit that moment right and they sound fantastic together. I also like how they are more friends than before and are really helping each other out.
Kurt
Firstly, he's back at McKinley! Makes me very happy since I like this new and improved Kurt. He isn't all over Finn now since he has Blaine now and I just overall like him better. Chris Colfer is getting a lot better at being him, especially with those comedic lines! He also seems to be mutual with everyone now and he's not getting pushed around. Though, I hated when he won Prom Queen! Whoever thought of that... I'll punch them in the face! I love his line "Eat your heart out, Cate Middleton!" That was great. So yeah, he's a new favorite character of mine.
Blaine
It seems everything with him is connected to Kurt. I'm sad to see that he isn't singing with the Warblers, but lately I wasn't a fan of his solos since they all sounded the same and it was just too Broadway, but I love his performance at Prom. I think he may sound better singing with girls. Besides that, I hope Kurt and him are going to be around awhile since the chemistry there, while not the usual chemistry boosts the plot.
Santana
Poor Santana! She finally told Karofsky and Brittany her secret, well they already knew, but they truly knew now. I'm so glad she's accepting it, but still hiding it. I like how she isn't so much of a jerk anymore and has some decent storyline now. I still don't want any Brittana, I prefer her with guys. And on a singing note (Haha I made a pun) the duet of Dancing Queen with Mercedes was awesome! Really sounded great!
Sam
I think its great to see more focus being put on him. And this focus is on a very emotional aspect of his life. Poor guy... no longer living in a house but a one-room hotel with two siblings and him being the main caregiver while his parents look for job. The moment where he broke down in the room with his sister was probably one of the saddest moments in Glee history. Yet, he is still pulling out great numbers with the other guys!
Brittany & Artie
I just thought to combine these two since a lot is bouncing between them. They are on and off, boyfriend and girlfriend. Unlike most, nobody wanted them together, but I really like this relationship. It's sorta cute. I loved their picture at prom, adorable! I also loved Artie's heartfelt Prom proposal, but he shouldn't have called her stupid so I think he needed to work a bit harder to get her back and he did and did get her back. So happy all is well! Then, while all this is going on, Brittany is having Santana trouble. I hope she understands while Brittany loves her, she likes Artie more and Santana can find someone more like her.

So love them two! And Lord Tubbington with Fondue For Two!
Mercedes & Lauren (& Puck)
Another combination... I'll start with Mercedes. She seems to be a bit at war with herself. She seems to have a self-confidence problem. I'm glad Lauren stepped into help, but luckily she really did discover herself later. She truly is better than she thinks. Very proud of Mercedes!

Then we have Lauren who is a bit too high on herself with the whole Prom Queen and King thing. Though I'm glad she brought up Lucy Caboosey to Quinn. It was eye-opening. And I'm pretty good with Pizes, so all good with Puck, not too much to talk about him with Lauren taking the spotlight.
Will & Emma
Now, to the adults. A lot hasn't been going on with Will besides some relationship problems. He was dating with Holly Holliday, who left and is afraid of commitment, so none of her anymore (sorta

) Now, Wemma is opened again! I'm glad he is trying to help her with her break up from Carl and helping her discover she needs help with her OCD. I'm so glad we are seeing a more emotional and serious side of Emma, not the crazy OCD we originally saw her as. I think Wemma may be my favorite couple now.
Then, just to end it off, we have the legion of doom consisting of the devious Terri (was) Schuester and Sue Sylvester. I'm getting nervous about these two being in cahootz! Who knows what could happen in the coming year at Nationals with them?
So yeah, I'm really enjoying Glee again after writing that much.
