Warner Bros only on the hook for 25% of Godzilla's budget, the rest was funded by Legendary so they won't lose much.Detective Pikachu is only being distributed by WB, again funded by Legendary. The only big loser was Lego Movie 2.
The second half of the year looks a lot stronger which was the case last year as well. I think they have a wildcard in Doctor Sleep, an adaptation of the novel and also the sequel to The Shining.
