E:FC Review:
This part goes for the first season: E:FC was one of the most promising science fiction series I ve ever seen. The talons where so completely differnt from all the other alien races in other series. These were no humans with cheap makeup in the face (star trek anybody?), or the nasty nasty aliens from trash sci fi. This race were different. They had their goals, they had their owns definition of moral. But even though they have made "mistakes" in the first season too you always believed that they wanted to help the people. But not only the talons were good. The leading character (Boon), a spy working for the talons and the resistance at the same time. Wearing a alien life form as weapon, lost his wife due to the deeds of the talons, getting a good friend of Da'an. This character was really promising. So was Sandoval, who acted like he acted cause he had a working CVI. IMO the best story of the show was Sandovals freed from the CVI for a short time. Thats were you were able to see the real depth and tragedy of this character.
Now to the later seasons:
I hate them. They destroyed everything that was differnt about E:FC. Just take the new main character Liam. This guy got no past, no personality and he even loses his alien side! "Wheres your shakarawa liam? Oh, I lost it..." DOH!!! And on the top of this the talons became more and more the evil aliens we all know from thousand other science fiction stories...
I suggest you watch the first season of this series. Its really worth it. But then forget it. Dont watch the later seasons. They are destroying everything.
