Pretty sure it will catch Force Awakens. The next few weeks are quite devoid of any movies that will challenge it for ticket sales. Then, end of the month you have Godzilla and Dark Phoenix the following weekend. It should cruise over $1B dometically and $3B world wide without much issue.
I saw it over the weekend and it was o.k. My youngest kid didn't love it either. Of course, her favorite is Captain America AND she knew all the spoilers about the movie already, so I'd bet that factored in heavily.
Movies with time line angles to me are always just cop outs. There are dozens of open ended, unanswered questions that arise from time travel and I think it's just weak to use this as a convenient out. They did an alright job trying to explain it all, but I'm not sold on it. And I mean, Stark is able to run a computer simulation to solve time travel in a matter of hours? Right.
I do like a lot of things Marvel does with these movies. Like the kid at Starks funeral at the end, immediately upon exiting, my wife is on the internets to find out wtf that is. Plenty of other little tidbits sprinkled throughout to spark conversations and build theories - I think that's super smart. What I hate is the after credit scenes. If there weren't 15 minutes worth of credits, fine, but ffs, once in a blue moon, drop one in there - wtf wants to read the rolling credits of the third crew of computer animators other than their family I guess. Once the movie is over, I'm out and on youtube to see the scenes I 'missed'. Anyhow, that's get off my lawn brought to you by guru_007
