See it if Appreciate theatre that deals with religious themes in unusual and provocative ways.
Don't see it if you don't like lots of language. Very intense. Ideas are sometimes hard to follow.
See it if you like the Narnia books for something completely different from CS Lewis.
Don't see it if you're skittish about hell and its inner workings.
"Some novels are more stage-worthy than others, and C.S. Lewis's 'The Screwtape Letters' is not among those that are. As adapted for the stage by Max McLean--who also directs the production with a flair for the grotesque--and Jeffrey Fiske, C.S. Lewis' 'The Screwtape Letters' is an unfortunate jumble of gibberish and gobbledygook, told at breakneck speed by Brent Harris, who is playing His Abysmal Sublimity Screwtape."
"It actually makes for a fun evening. ‘Screwtape’ is deliciously evil...One of the more interesting, if uneasy things about ‘Screwtape’ is that for a while it actually gets you to root for the devil...Finally, while this is a serious play at heart, there are lots of humorous moments.”
