5 Stars: Loved it.
For the shows that gave me a pleasant emotional reaction.
4.5 Stars: Liked it.
For the shows that didn’t quite give me an emotional reaction, but still deserve more than a four star rating.
4 Stars: Very Good.
For the shows that are well done, but didn’t work for me personally.
For the shows that fall in between three and four stars and have attributes of both.
3 Stars: Enjoyed it.
For the shows that didn’t win me, but are still worth sampling.
I will rarely go below 3 stars, unless it’s something that doesn’t have any saving grace. The only way I see that happening is if a troll creates an audio drama and asks me to review it.
