That's the dumbest thing ever. I can bet you more money is made on Sundays than on Fridays. Everyone is at work on Fridays! Who even goes to movies on a Friday?
Anyway, Disney film distributor David Hollis said a good opening for the movie would've been $20 million, and as of Sunday morning, it had $16 million, ONLY $4 million short of that amount. It's not a "flop"!
Plus, the audience has spoken! Most of Divergent's audience HATED the movie, and hopefully they'll make a turn around and see MMW next week. Also, spring break is coming up, and that'll bring in a lot of money.
