I am more of in the $80M-$90M range OW, that said it is the first major tentpole of the year (no offense to The Last Six and Epsilon), the space opera wave is still the strongest in the game, and reviews are still good at a 72 on MC (as the people who loved it really loved it and the people who disliked it really disliked it).
Though I do think 2LBH will hurt a bit, there’s plenty of room for them both as seen with Incredibles 2 and Fallen Kingdom, Jurassic World and Inside Out, Despicable M3 and Homecoming, etc etc. 2LBH won’t have real competition until Splatoon and even then it’s late in the run and I am thinking more of the lines of a $50M-$60M OW for the Inkling squad and even then nothing in the summer other than Sylvarius and maybe Static Shock targets families. GLC doesn’t have real competition until COD2 and that is somewhat limited by the R rating it has and In The Valley is more of the drama catergory. Both Portal and Psyren will be over/Under $100M. GLC is sailing smooth until One Punch Man.
I think both GLC and 2LBH mainly due to how weak the May to June calendar is. My guess is probably a run around Doctor Strange for the former and still over $400M easily.
