Well if you'd bother to watch the showdown [http://boxofficemojo.com/showdowns/chart/?view=daily&id=superhero2014.htm] on bom, or learn how to read the numbers you'd understand why it's failing.Kumagawa Misogi said:Just looked them up on Box office Mojo
TWS had 3938 theaters and made 24,130 each
ASM2 had 4324 theaters and made 21,186 each
TWS had 9% fewers theaters but made 12% more for each theater.
Understanding all that goes into estimating a box office weekend is complicated, but part of what makes that opening box office what it is happens to be theater count. Sony got more theaters expecting to be able to make more money because of more interest in spider-man. Not being able to beat Cap when you have a 386 theater count lead is a big deal when measuring a movies success. TWS is also not considered actually in the Summer Movie Season, and ASM2 is considered to be the first actual film to start Summer. Part of this is Summer Movie Creep, but Summer is supposed to be the driving factor in the Box Office when targeting kids that are typically in school in April. Opening on final exam week was also probably not a smart move on Sony's part, but that's why summer creep is bad.
The Monday after is also a big indicator for the remaining success. The weekend percentage deltas are normal for each franchise, but the First monday for TWS was a 73.5% drop where for ASM2 the drop is 77.8%. Now compare that to AMS 57.7%, or the first Spider-man film of 65.3%.
Cap isn't designed to be anything other than a 150 to 200 million dollar franchise, and as such it's meet expectations and exceeding them in many cases. The concern with Cap has always been that a character that wears the countries flag isn't going to go over well with the General Audience. Digging down all the way to the Ukraine just to find countries that Spider-man beat Cap isn't a good point in your favor because of that very issue.
Spider-man is supposed to be a 300+ million domestic franchise. He's had 4 plus titles running each month, and had been the top selling character of Marvel for decades though currently that's been wavering. If ASM2 only barely breaks 200M domestic it will be a disappointment, and that's exactly where it is headed.
