Uber-love:
Garrus Vakarian : the ultimate bromance.
Urdnot Wrex : funny, well developed and totally badass. Also, another bro.
Javik : hands down the best ME3 character. He's a supremacist with very questionable morals, yes, but he also has a philosophy and he's a tragic figure. And more importantly, he's a complete ******* and one of the funniest character of the whole trilogy. His "They used to eat flies" response to Liara is one of my favorite line.
Love :
Urdnot Grunt : I tried not to like this guy, as I thought he would be a rehash of Wrex. I utterly failed.
Miranda Lawson : There's a superficial side to my love (gorgeous character model, unbelievably sexy voice), of course, but really, it's the personality that does it : badass and confident ice-queen with a sensible side and an interesting background. I like to take Miranda pretty much everywhere, and she's usually my LI.
Mordin Solus : What's not to love about Mordin? Pragmatic scientific genius that can sing? Yes, please. Not to mention he's really funny, interesting and always questioning himself. I really liked how he finally changes his views on the genophage in the third game, although he had to sacrifice himself ;_;
Legion : my love for Legion has no bounds, and everytime I hear "Shepard-Commander", my heart melts. He's the sole reason the "destroy" ending is such a moral dilemma. I still choose it, but damn it, it's hard and it takes a lot of headcanon.
Like :
Samara : I really like the intimate relationship she and my Shep have. I just find her fascinating, and there's something about her eyes...
Samantha Traynor : let's just say she succeeds everywhere Kelly fails. I would have liked to date her, but I unfortunately play a male Shep.
Jack : I finally gave her a chance in my last playthrough, and it turns out she's a really good and well developed character.
Ashley Williams : I finally did a whole playthrough of the trilogy with her as my LI, and yeah, her role in ME3 is really not as good as in ME1. Too bad.
Don't like/Boring:
EDI : As much as I find Legion fascinating, I really don't care about the sexbot. I ignore her completely in ME2, as she gets on my nerves.
Jacob Taylor : Jacob is alright ; just not very interesting.
Kaiden : I heard he gets better in ME3. I wouldn't know.
Joker : I have a love/hate relationship with Joker. I find him funny, but he tends to get on my nerves, and I have absolutely no incentive to go talk to him directly. Also, I will never forgive the way he disrespects Legion in his loyalty mission. NEVER.
James Vega : No need to explain, but I have to say he's growing on me.
Thane Krios : he *should* be interesting, but his long speeches and his voice bore me.
Talizorah Vas Normandy : yeah, no love for Tali here. I never cared so much about the Quarians. You have created conscious and intelligent beings : that's all you need to know to not treat them like disposable tools. Bunch of assholes.
Liara T’soni : I feel bad placing her there. She's an interesting character and I like her, but her personality is, unfortunately, really boring.
REALLY Boring:
Kasumi Goto : bland and uninteresting character. Could do without.
Steve Cortez : why is he on my crew?
Kelly Chambers : didn't talk to her at all in my last playthrough of ME2. That's how much I didn't care.
Hate:
Zaeed Massani : no redeeming qualities whatsoever -- I hate everything about this guy. Even the accent.
