Cap had April pretty much to himself though.
Spider-Man dropped below an R-rated comedy for week 2 and has Godzilla and X-men to deal with for weeks 3 and 4.
...hence my comment about Spidey having a long way to go.
Cap's been going for 6+ weeks now, and will likely get another week or two before most theaters go ahead and let the film go.
But Spidey's cutting it close to the start of blockbuster season, and it shows. Even if it survives beyond week 4, it'll have the one-two punch of "Maleficent" and "A Million Ways To Die In The West" for week 5, "Edge of Tomorrow" for week 6, and "22 Jump Street" + "How To Train Your Dragon 2" for week 7.
Unless one of those movies absolutely tanks, they're going to pull viewers away from the "older" films, even if only for a weekend. Spidey might be able to fend off everyone else, but he'll take a pounding in the process.
