Just want to point out that while TMNT is getting really bad reviews from critics, the general audiences seem more divided on it than anything. Rotten Tomatoes gives it an 18% fresh rating from critics, but a 64% fresh ratings from audiences.
For comparison, Transformers 2 got 58% from audiences, Transformers the First got 86% from audiences, DOTM got 56% from audiences, and the new one got 55% from audiences. So, other than the well-received first movie, audiences seem to like TMNT more than the other Transformers films.
As for the box office results...I'm not surprised or disappointed. In fact, the only thing that surprises me is that Guardians of the Galaxy managed to beat out TMNT in their respective opening weekends.
For more good news, look at it this way. Guardians had a developmental cost of $170 million, outside of marketing costs. Let's figure another $30 million for marketing, to make the total $200 million. Only two weeks in, it has made over $175 million in North America, 87.5% of my estimated budget. Mind you, that is just in North America, and just in 2 weeks.
Meanwhile, TMNT is projected to make $60 million this weekend in North America. Not a small amount normally, but GotG performed better its opening weekend, and TMNT has a budget of $125 million, not counting marketing. Using the same $30 million estimate for marketing, that brings up the costs to $155 million. Assuming it reaches the projected profit, it will make back 38% of its money. That's nowhere near as good as GotG is doing.
Now, if you want to go worldwide, it's an even bigger difference. Guardians has currently made $313 million worldwide. Using my estimated budget from before, and taking out any of the minutiae that goes into figuring out profit besides (sales-budget)/budget=profit percentage, it is looking at a 56.5% profit. Already.
TMNT has made $93 million worldwide. Using the same methods as Guardians, that sets its current profit at -40%. Yeah, as far as box office goes, Guardians is totally wiping the floor with TMNT, even making less money this week.
