Eric was more interesting when he didn't speak much and kept that air of mystery about him. Now that we know so much of his backstory, both the character and actor just come off as very bland.
God, you got that right. So many women find Skaarsgaard highly sexually appealing. I just don't get it. He's bland. He's skinny, he doesn't have a deep voice. I just don't get it.

My biggest complaint with the show has always been the number of storylines that don't really relate to each other at all. It's like they have an A, B,C,D, maybe an E plot each season, and, while A & B come together, C,D, and E may do so only tangentally or not at all. That's bullshit writing and it makes for a cast that, while high in variety, comes across to me as far to many for too long. It's one thing to have recurrent characters, it's another to set it up to have what amounts to several subcasts within the entire cast.
Heroes. Too much cast. No coherent plan. No cohesion of story. Throw everything at the wall. See what sticks.
