I'm on episode 5 of season 2 and into it. None of them are really that likable. I love Ruth. I think Ozark has a lot of characters that are serious and cold all the time because Marty and Wendy's lives are constantly depending on whether they can pull off whatever is thrown in their faces. They are in a constant web of danger just trying to get out and live a normal life as a family. Also Buddy is likable to me lol
At the end of the day likable characters aren't that a big deal to me atleast for that type of show. For a show like Ozark what matters is that the characters feel real and have real motives.
Marty
Ruth
Marty wife
That blonde lawyer
Buddy
Marty’s son
Red neck dude who grows the opium
Wyatts not bad
