Well yes. I think Christopher Robin will suffer because of Ya Veremos. I can only hope it has some staying power as it does look good (although of course I haven't seen it, definitely planning on going during the weekend)
This summer has not been that memorable. Other than Avengers, Incredibles or MI:VI I don't think there was anything REALLY exciting (Deadpool 2 was Ok, JW:FK was meh, HT3 was funny but not FUNNY, Ant-Man delivered... didn't see Solo or Skyscrapper and don't plan on seeing Equalizer 2 or Mamma Mia). Not a very memorable time for Blockbusters
