Theon Greyjoy will split opinion. Some will probably like his character and impact on the show, others will hate him.
I think Asha Greyjoy will be popular. Melisandre too.
I like Davos but I'm not sure how popular his character will be. It'll depend entirely on how much screen time he gets and whether they decide to give him as much importance and emphasis as the book does.
Depending on the screen time, Asha could be pretty popular. Davos and Theon, I guess it depends on whether you like the Starks or like the Lannisters. Some will like Melisandre, but maybe it's just me, I don't think she'll be that popular. I forgot about Arya. She's my favorite character from the entire series.
In general though, I'd be surprised if Dany, Jon Snow, and Tyrion are not the three most popular characters still when the show catches up to where the books are right now.
