I've realised that Toni Collette is one of those actors for me, I'll give something a go even if it's not my usual thing because she's a good actor and also seems to have sound judgement of what's a good script/idea. I've just started watching Pieces of Her and it seems pretty good so far (one episode in).
Also Joshua Jackson, although I haven't watched The Affair yet. And Susan Sarandon, although she's around much less these days.
People who put me off a bit are Melissa McCarthy, she's a really good actress but she's agreed to star in some terrible stuff so I always make sure it's going to be worth watching before I give it a go. I find Laura Linney, Juliette Lewis and Jason Bateman vaguely annoying in almost everything so generally discount anything they are in.
