The movie started out with an interesting story and likable characters. Then all originality came to a grinding halt. It was just contrived and dull. I would not recommend this movie.

Even the most fanatical of religious zealots would be hard pressed to match the anti technology fear that seems to dominate the quivering mass that constitute Hollywood screenwriters these days. It seems that experimentation and innovation are the purview of arrogant scientists, who will inevitably be punished for the hubris of wanting something better for their species. The drivel that this movie serves up clearly tells us; There are things Man was not meant to know" or "Man should not attempt to cheat death"

Firstly, what is the purpose of the dog character(other than a proof of success of the experiment)? You have the Lazarus dog not eating, breaking out of cage, more interestingly and more eerily, standing beside Zoe(Olivia Wilde) while she's sleeping--which is quite a strange image,I think I can see the dog's penis when it's standing on her bed. I guess all of these are to set the mysterious mood.(Did I just answered my own question?) But the later half of the movie the dog doesn't do much except being disappeared by Lazarus Zoe.I'm still not sure it is a sci-fi or a supernatural movie. I feel it's like from fictional scientists' point of view to look at supernatural phenomena...if what I say makes any sense.I think essentially this is a love story. Because Zoe loves Frank, so she keeps waiting for the wedding, keeps wearing the engagement ring. That is what gets her electrocuted--she forgets to take off the ring when she connects the main switch. Because Frank loves her so he has to bring her back. Then because Frank can't stomach the new Zoe so he decides to kill her.(but fails and gets himself killed by her) Why do I have the feeling that Zoe loves Frank much more than Frank loves her? I suppose that's the reason Zoe brings Frank back at the end, because she still loves him. P.S. I like this Zoe character a lot; Evan Peters' performance is great; Sarah Bolger is gorgeous.

A group of medical researchers discover a way to bring dead patients back to life. The Lazarus Effect suffers from a boring plot and characters that has been done more than 10 times every year it's not scary or even interesting after a while the only good thing about it it's without a doubt Olivia Wilde as Zoe the girl who came back from the dead and started killing her friends. This is the first time that i ever watched a horror film with some potential but the writing is just so mediocre and the characters are so boring that it ruins the whole experience that it makes you want to see every single one of them get killed by her at times it doesn't make sense also especially the ending when Zoe brings back Frank for some unknown reason i would like to see a part 2 but only if it was interesting and the characters were written better. I will give The Lazarus Effect a 5.5/10.
