I'm willing to play it more passively being there are NO reads on villain. I don't like to guess that he didn't hit the 4 card straight....I would also bet more on the turn. The 200 bet is small compared to pot and it looks very weak....You do have top set but as we all know, top set doesn't beat a straight. I'm not saying he is beat here. I'm just saying its very probable villain had pair with a redraw.
