"Shanghai Fortress" received bad reviews before it was released, because of the protagonist?

Look at the problem objectively Not just the protagonist, this is the main reason. There are some secondary reasons.

First of all, from the perspective of a third party, the main reason is the role. The protagonist of "Shanghai Fortress" chose Lu Han. Although he is a traffic star, in today's society, most people have a kind of resistance to traffic stars, especially this kind of sci-fi theme, which is usually played by powerful tough guys, and is not in tune with Lu Han's plays. At the same time, because Lu Han's previous film and television works have little influence, they have not been loved by the public, and the public will be subjectively right.

At the same time, The Wandering Earth, a similar film, performed almost perfectly, leaving a deep impression on the public. They will compare with each other and have certain disadvantages.
