Notice how its the only movie with a major drop from sun-mon. Does anybody else think they may be underestimating it? (although its better to underestimate your movie)
I think either this is underestimated or the cave is over estimated.

I don't they they are underestimating it. The sneaks inflated the Saturday and Sunday gross. It will just go back to normal on Monday.

But, I do think March of the Penguins is underestimated. Why would it drop 27% today. Family movies never do that.

oh i didnt know there were sneaks on it.
but yeah penguins i think is being under as well. (it probably dropped as much as charlie)

Did Grim had sneaks on both Saturday and Sunday? Dang, if that's the case Grim is doing very bad. Let's look back of what it might have made if there's no sneaks. With a Friday gross of $1.77m and an estimated gross of $1.109 on Monday. Let's calculate what it would have made.

Fri: $1.77 (given)
Mon: $1.109 (estimate) (-37%)
Sun: $1.76 (-15%)
Sat: $2.07, that would mean the increase is only about 15%
__________________________________________________
Total: $6.71 for 4 days. (over 55% drop even for 4 days!!)

Another case would be, if I raised the Sat increase the I'll have to raised the Mon drop.

Fri: $1.77 (given)
Mon: $1.109 (estimate) (-45%)
Sun: $2.0 (-15%)
Sat: $2.35 (+33%)
____________________
Total: $7.23
Hmmm, not good.

Grim could of made it then onto the biggest drop list if there was no sneaks possibly.

I knew they were underestimating it!

Good Catch.
