Why is this movie so overrated ?

Rating: 1/10 (17 March 2018)

I am against discrimination. But I honestly think this movie is overrated just because there is a black super hero! ( It's also a bit discriminating towards all others that there were only black actors but ok it's not the topic here)...
I hardly could stop my husband to go to the movies because he said there are really good reviews. But after seeing it, I wanted to check IMDb. And I wish I checked it earlier... so many people have already written my thoughts. So many 1 stars...
well, it's your choice of course so no spoilers from me...
