Why does CGI still suck

I thought CGI was now good enough to replace real actors and sets but after watching The Hobbit recently, I am not so sure anymore.

The orc foot soldiers (which are actors in costume) look way better than the CGI leaders. The CGI movement looks slow and off putting and theres a distinct lack of detail. The lighting is also all over the place.

Can CGI ever reach a level of realism where people don't realize what's real and fake? How many more years will it take?
