In a random movie? No. In the adaptations of those particular books? It is a big part of what matters. They're plot heavy and I read them for their stories. I am sure the series make some stylistic choices, and I know at least some of those actors are going to be doing good work - how much of those is actually present in them though, remains to be seen, and I am sceptic that it should be enough to warrant a thirteen hour watch on its own. If I rewatch Blue it will not be for the plot, but that is not the case of most of the movies I watch, let alone these specific ones. I look for stories, worldbuilding, rich dialogue, wit. I am driven towards words and action. Cinematographic flourishes are great but they usually only enhance a movie I already like.
Besides, when I watch adaptations I spend the entire time mentally anticipating every thing that is going to happen next, and comparing the adaptation to the original, which can be quite annoying.
