Ex Input:
I am a fan of Dan Brown and his books, but "Angels & Demons" just didn't make it. There were many loose threads to be wrapped up as well which ended up left dangling. Why did Angels have the gift of telekinesis? Who was Mallozzi? What does he really know? Etc. etc. The big mystery at the end is never solved either, except for in Brown's own head (which got so tedious after a while).

Ex Output:
Bad review


Ex Input:
I think what makes these so good are the interchangeable tips.

Ex Output:

Good Review
