Based on some of the reviews people wrote they said they didn't like it much or dropped it after a few episodes but i loved it. The story was interesting, the characters were unique, and it was just amazing. :D I suggest it.
Eavh charatcer was unique and was intresting to see how they would handle the passengers. The last episodes that take place during christmas time are the most enjoyable. The last episode, i thought, could have been better. Or atleast have one more to wrap up. Over all it was a good one to watch. I finished it over a weekend :P
