$135 million is VERY good to be certain; but again, I have to wonder if Warner's and DC are STILL disappointed in that earlier (just two weeks ago), entertainment industry pundits were saying Suicide Squad could open at $145 - $160 million domestically; and even with the $135 million it received, here's another big budget DC superhero outing that WON'T break the 1 billion dollar worldwide box office ceiling.
Again, that film is definitely going to make a profit, don't get me wrong; but I'm sure WB and DC are still looking for something the critics and audiences really like - like a number of the Marvel Studios outings that have both had good critic and fan reviews and brought in over 1 Billion+ box office worldwide (and gotten good pay channel and subscription channel play at that stage too.)
STB overall is a well reviewed film. That might help it recoup more when it gets to the Pay and Subscription Movie Channel phase of it's revenue generation for Paramount. Time will tell.
