It really is kind of bad.
It was! I watched it primarily because of all those jokes Jack Benny made about it on his show, and I wanted to give it a chance, but it really is not very good. So much makes no sense- why would a radio show have a complex automated coffee advertisement thing no one can see? Since when does coffee put you to sleep? How come the crowd threw Jack out of the swing club for his trumpet playing, when he was playing just as well as the rest of the band? Why would he climb the ledge when the crooks threatened him, when he knows no one can harm an angel? And even though I knew it was a dream the whole while, the sudden ending still felt like a cop-out.
Still love Jack Benny, but I could see why he got needled over this movie. It's also no reflection on any of the actors, they did what they were supposed to do but the plot is just too goofy. The special effects are really great here though, especially in the giant coffee pot scene. That part alone is worth watching the movie over.
