This might be just one of those cases where the pilot is far better than the rest of the series but this first episode is just impressive.
The story is really original and every character in the show has the potential to be a bad guy/girl. I was specifically impressed by Erica Christensen who plays a role with more depth than in Parenthood.
As per Jeremy Sisto and Ed Westwick, both are giving an excellent show.
This story has a real potential and can run for many seasons if the quality of the scenario doesn't deteriorate after the first 10 episodes... as it's often the case (with the producers firing the expensive writers and directors and replace them with amateurs).
And the music is good too.
