I like the idea of the show, but the writers need to do better research (I'm looking at you, Brazil storyline), and some of the actors need to step up their game a bit.


Read the book, if the series is only half as good it will be awesome, can't wait.


The previews on the radio and television commercials make this sound really good and interesting. Can't wait to see this show.


A great premise to a series that very quickly fails to achieve it's potential. Season one is worth the watch but it quickly goes downhill. The writing is mediocre, the acting has it's flaws, Billy Burke (no matter how charismatic) is still Billy Burke, the pseudo-science and the apparent fact people don't know basic biology, situations that are unrealistic even for the subject matter ([spoiler] can you imagine all insects being against us? humanity would be done in a day, a gorilla that can't bash in a stupid elevator grate, etcetera [/spoiler]). I'm still gonna watch season 3 for completion's sake and I'm still entertained a bit but this could have been so much more. Edit: Upon finishing Season 3 I must disagree with most/many people that it was the worst season. Besides a couple of annoying writing errors I enjoyed Season 3 way more than the second one. It got a bit annoying that a certain person kept surviving and that we, ofcourse, will never know what would have happened in Season 4.


So, reviewing after 3 seasons... Season 1, good. Season 2, weird and makes you think at times, should I be watching this. Season 3, well, it's a mix of 1 & 2. No one ever has jet lag? :)


I just watched all the episodes of season 1 and 2. [spoiler]I hope Chloe is still alive somehow ;([/spoiler]


I am a fan of fiction and scifi movies and series but this one is the most ridiculous one I have ever seen and I seen a big part of them. The people keep coming from the dead, the main characters are invincible, The plane never get fueled and never have the permission to land but it lands everywhere in the planet although it enormous. Although they are shot, stabbed, floating in a tank after numerous bites and from a monster I must add he is fine no repercussions. In season three thousands and thousands of hybrids are attacking the facility a team still got out as if nothing, while others are still battling. I can't understand. And the most ridiculous thing the villain after a procedure in her spine by the way her back is open 6 inches a hole like Niagara Falls in her neck, a concussion she just jump back up and run away and mind you no blood on her not even a drop. I don't know who wrote this, but it's like the asked small children to write it because the imagination is the same.


Season 1 was okay but later on I just couldn’t stand the series


Am I the only one that feels like they were hanging when the show ended?


:( another good show gets the boot
