But would franchises be so successful commercially if that wasn't even somewhat true ? Hollywood is going down that path because it seems to work quite well financially, if it's fundamentally flawed then the problem will sort itself out quite quickly. Could it be that this tendency, and the success of TV series (at a time when TV isn't doing particularly well) actually points to a difficulty with the traditional movie format ? Maybe it's just the case that universes/longer time frames afforded by franchises and series make for easier storytelling than the constrained 2/3h continuous cinema sitting ?
