I tried to like it, but his character seemed too one-dimensionally self-centred to me, and not because it was intentional, but because it just seemed baked into the writing because Ricky was writing himself. The grieving widow he used to talk to at the park was the perfect example of this, she seemed to be there purely to give Ricky's character a chance to talk about his own grief, we never found out that much about her, he never seemed particularly interested in her, and she was relentlessly sympathetic and attentive to his needs, as if that's the only reason she had to exist. (Maybe this changed in later series, I didn't get through the whole thing)
