When you get over that everyone looks like a tale pale man with a moustache and that you will not be able to tell them apart and that the plot won't make sense all the way though, it's actually quite funny! Especially Eugene Pallette (one of the few non thin pale men with moustasches) and the running gag of the doctor never getting to eat his lunch shines!

My favourite line is: "Why did Cole lock his window? Especially when we know was a fresh air enthusiast!"
