I definitely prefer steelbooks with title on the front, and it does not matter here whether it is well known movie or not, someone who has not seen the film yet and will look on the front cover will not be know on what movie he looks.
For me is the same as with a book, I can not imagine all the books in bookstores without title on the front. The title is the most important part of any movie or book and well designed artwork on the cover should just reflect it not replace it.
I just hope that someone else will not go further and in the future will not want to remove the title also from spines, then we start to get no name products
