Big mistake killing Derek he is a great actor and since his leaving of the show it has gotten worse there is NO chemistry between ANY of the new couples and the show's now do not come close to the ones where Derek was involved. Sadly this show is on its last stretch with nothing more to offer. Big Grey's anatomy fan sadden by the last few seasons knowing that the end is coming and it ends no where close to where it started. Shame on you who wrote this series to death could've been greater but the writers settled for less. 😡
