It's not bad, its good. But no where near as good as to knock Avengers train off the track, which was the context to begin with.Charlie and the Chocolate Factory grossed $474,968,763 WW which is not bad. However other than Alice all his mega hits have have been within the Pirates franchise.
Regardless, the genre and look of Dark Shadows seems closer to Sweeney Todd (I know its not a musical but still)/Sleepy Hollow than Charlie. A number between Sleep Hollow and Charlie seems like a good bet for DS but its not enough to stop the Avengers juggernaut.
Not talking if Depp/Burton flicks are flops or hits or earners, we're talking about Dark Shadows in context of effecting Avenger's grosses and hence its legs to reach the 1B mark.They still make their money back here and OS they always make good money. Except Sweeny but we can all understand why...
