wasn't that expected. there was inflow of films getting big screen count since 3rd weekend till last weekend. That slowed a bit this weekend, and of course Father's day. Now it will start improving in its daily grosses over Infinity War.
I had already speculated that, so still its not going to beat Avatar.
Need re-release or simply mass fan events across world, all we need is 3mn more viewers, that's less than half of number of people watched its trailer in first 10 mins of launch.
