Yeah lets not forget that it is a Marvel movie. This is a relatively unknown IP in the West, from a relatively unknown director. Its not really comparable. A good comparison is John Carter, relatively, Unknown IP, with a unproven lead actor and look how well that went down.
It was a Marvel movie with no visible ties to the MCU outside of Thanos about a D-List group of heroes that no one who wasn't well versed in comics had ever heard of.
