Hell.. even some people love Littlefinger, I expect.
I do. He's my clear-cut favorite villain on the show. And quickly becoming, I daresay, my favorite character, period. I've always ranked Tyrion and Dany as my two favorites, but they've each become a bit boring lately, now that they're sitting in such powerful positions. I found them far more compelling when they were struggling--struggling to gain power, in Dany's case, and respect, in Tyrion's.
I admit Petyr possesses the most punch-able face in the seven kingdoms, but he's a master manipulator and has grown to be the most interesting character on the show. A big part of Lord Baelish's evil charm, is the actor who plays him, Aiden Gillen--he's positively brilliant in the role. I'd put him up there with Dinklage, Headey, Dance, and Rigg as the best actors in the series. Game of Thrones has a lot of capable to good actors. But these few I've mentioned are extraordinary, and can tells us more with their eyes and micro-facial expressions than even their dialogue.
Gillen, like the aforementioned standouts, is a treat to watch, because I derive pleasure on two levels: one, I get to enjoy what his character is saying and doing, and consider how it advances the story; and two, I get to marvel at his (the actor's) performance. With so many of the other characters on the show, I really just enjoy how their words and deeds advance the story. Their acting is good enough, so as not to be a distraction, and to be fair, may have some exceptional moments here and there--but they don't glue me to the set like Gillen and the others, where I hang on every word, and don't blink for fear of missing some glint in their eye or hint of a smile. Let me put it this way. I invariably eat dinner while watching Game of Thrones--but my fork is set on the plate when Littlefinger shows up.
