Wasn't. Wow. This show could have been SO MUCH better than it was. It SHOULD have been so much better than it was. It had the potential to eclipse Dexter because revenge/justice wasn't what drove it; mercy was what drove it. Or should have driven it. Instead, as other reviewers have pointed out, it devolved into the most absurd non-believable soap opera ever. This series has more stupidity than a non-stop weekend run of slasher movies. The story arc with Ben was laughably stupid. The same with Des. The same with Grady. The same with Olivia. And Annie. And...and...and. What a total waste considering how great this show could/should/would have been had it been in the hands of skillful producers, writers, and directors.

Mary kills people started out with potential. The Pilot episode held promis as the new show about Female Kevorkian.And it looked like it had something to offer about a provocative real assisted suicide issues in real life. However, it Very Quickly changed it's tone from that, and became your usual soapy drama involving doctors, cops, and drug dealers. Such a missed opportunity. The writers could acctualy created interesting meaningful drama over the show's subject but chose to go to shonda rhimes's sloapy soap drama.It really showed that the writers haven't done actual learning/research regarding this spesific issues. It got murky around the middle, the cop stuff was embarrassing, the euthanasia issue and it's complication got totally wasted with an ending that any viewer could see way before the last episode.

I really enjoyed the first episode, it has great potential original script, great premise to explore and even though it deals with assisted death it is not depressing - there is a great blend of darkness with humour. Stellar acting from all involved, especially Jay Ryan, Caroline Dhavernas and Richard Short and it left me wanting more. The characters are all multilayered and believable and it has got great pace throughout. I cant wait to see what happens next and I cant see how the characters will develop and whether their viewpoints will shift as the episodes progress. If you want to watch a show that is original, fresh with amazing acting and well written check this one out

So far only the first episode is out, so this is based on that only. I don't know if I like this show or not. It's an interesting premise and the title character, Mary, seems to have a backstory that led her to what she's doing. What she's doing is helping terminal patients die by choice. She's an ER doctor by day, heroically saving lives. Her partner is referred to as a "former plastic surgeon", suggesting a past that didn't go so well. He also seems to have been an addict - they get the drugs they use to kill their terminal patients from his former dealer, who is suspicious as to what he's doing with the drugs. The plot gets more complicated when we discover that a patient Mary goes to visit is actually an undercover cop who is working on a sting to put her away. Oh, and her kids have discovered her stash of drugs. That's all in the first episode. There's the potential of good secondary plots that explain or elaborate on the story line. Some nice tensions. The actors are good, suit the parts. I just don't think I like them very much. There's no sense of altruism about what the doctors are doing - just money. Except...she starts to talk to the cop but then the conversation doesn't go anywhere. Maybe it'll come out a bit at a time. I'll watch again. There's definitely potential. But I'm still undecided if it's a keeper.
