I'm afraid they are not. However, if you consider the death of main protagonists and killing each other to be a happy ending for you, you don't have to be afraid. You will most likely get want you want. And more.

A happy ending would be a united Albion under Arthur's reign, magic being restored in Camelot, Merlin being recognized for who he is and getting his deserved place in Camelot, everyone surviving. This is not going to happen.
