How does this have such a high IMDB rating?

Rating: 3/10 (11 August 2018)

Fine acting and pretty technicolor but this makes me doubt IMBD's rating system. The plot was so trite and had zero sense of jeapordy. Made it impossible to really care what happened. Such a shame as it obviously had a big budget.
If you're looking for a good super hero movie go watch Man of Steel, Justice League, Dr Strange or both Deadpool's. This one could have been great but definitely fell short for me.
