A: Good Review

Q: This is a well-written short story that shows why horror was so popular in its day. It might seem dated and silly now, but back then it still gripped the imagination...well, not really my imagination, more of a desire to know what did happen. There are some grammatical errors with this title, which makes me wonder if it's just my copy, or perhaps I'm having trouble reading this, since the errors were there before I read it. The storyline is very good.

A:
Good Review
