I think in context it seems clear that they were simply rejecting it out of hand because of the cast. Ice Cube has made some terrible movies. It's ironic that in an attempt to leverage the irony of putting him in family movies he somehow became a kitschy family movie actor along the way. Now it's tough to take him seriously. And as Doug remarked the other day, it seems a lot of comedy folks are a little perplexed by the fact that Kevin Hart is in every damn movie there is today.
There was little chance they'd have gotten close enough to it to note the quality of the screenplay.
This is one of those tweets they don't need to see.
