I dont get the question.
So only make movies that make a lot of money? What if He just enjoys making them?
Also, Just anecdotally, murder Mysteries are one of the few Films my GF and in can enjoy together. So I look forward to These Films. There arent many New and well produced/good looking Films (even if the Script isnt that tight) that we both can enjoy together.
They are fun and have an old school charm.
