I'm going to challenge your numbers...
Disney has a far more favorable deal with theaters than 50/50. That 50/50 number is a thing of the past especially for Disney. Rumor has it on Star Wars films Disney gets close to 75% of the take.
Let's say for this film Disney is getting 65% which is a stretch, but possible. Disney has known for a while this was going to bomb and no one in Burbank lost any sleep over these numbers, so I don't think they spent 60M in marketing as rumored. I think that number is closer to 40M .
Even with my numbers and insight they're looking at least a 50M loss. Disney knew this one was DOA and a 50M loss isn't shattering, but nonetheless disappointing. Could've been 50M put towards polishing up the parks.
IIRC, Disney demanded, and got, 65% of ticket sales with TLJ, plus other demands were met if a theater wanted to screen TLJ. I don't know if they get better than 50/50 on other movies.
A $20 million domestic opening, on a $130 million movie, combined with almost across-the-board low review scores? Flop. Can't say I'm shocked, either. Who continues to green-light this crap?
