Anyone else think they did well with family resemblances?

I was just watching 1.06 "Heatwave," and I have to hand it to the actors and those who cast them.... You can totally believe the Millers are a family if you're paying attention. Jack Davenport's (Bruce) facial features are EERILY similar to Aaron Christian Howles's (BJ), really, and Susan at times really does look quite a bit like Laurie. On top of that, these pairs use the same kinds of gestures at times. It's really quite impressive!

I have noticed anything too similar with Janet, Roger, and Rick, but I'll keep watching. Rick isn't featured as much as I'd like him to be.

Speaking of Rick... Did he have a crush on BJ or was he just possessive of him? I know this has been discussed to death but still. Thoughts?
