I will do it starting next week. I did a cursory glance at some AMCs yesterday and it didn't sell too much, but this isn't really a film that will have huge upfront sales, even with it being based off a popular musical.
That's what makes me a professional 😎
And in all fairness, Sing 2 doesn't have that many shows. Outside of a couple theaters, Sing 2 only has like 2-4 shows per theater, so it only takes me a couple minutes to check, especially since a couple theaters have like...three sales or just flat-out none. Matrix will likely be a bigger problem, but it'll still likely only be like 4 shows per theater to check, at least pre-NWH's opening, so I don't see it being that huge a deal.
