This was supposed to be brand new, but it's not. It had some marks on it. It could have been used as an old CD or cassette tape, not new.

Ex Output:
Bad review

Ex Input:
As time passed on, more facts came out that made the story much clearer.

Ex Output:
Good Review

Ex Input:
Very interesting show that was never on any list of best shows. Great characters with good plots all centered around an alien who can actually speak human languages and communicate with people. The episodes are short so it's great for those marathons. Worth buying to watch before you go see Terminator Salvation.

Ex Output:
Good Review
