Query: Eh.....

The story was great, but the writing was very....uh....young. The characters lacked depth and maturity. I could see one or two immature characters, but ALL of them? For supposedly professional and well educated people, they behaved very unprofessionally and in a very reactionary way which never would have been tolerated in the positions they were in or the situations in which they found themselves. The whole story was entirely unbelievable. But the concept was interesting.
