I couldn't care less for any of the characters

It's amazing that none of the characters, except perhaps the victim's son (Miguel), looked like people I could sympathize with. They (under)developed the characters just to look suspicious and grab our interest developing theories, but the thing is that I couldn't care less for any of them and I watched up to the end because I didn't have anything better to watch on a Sunday evening. Usually I'd feel for the betrayed wife or the son of the accused for all they had been put through, but they seemed so artificial that it was hard to relate top them. And that court circus?! What was that? That defense attorney charged a fortune and didn't even bother to check on her client's background and why putting the wife to testify when he was under reasonable doubt? Just for the plot's sake. And why such good actors performed as if they had just graduated from Joey Tribbiani's soap opera acting classes? Those exaggerated looks and facial expressions with close ups for dramatic effects were so pathetic!
