None of that has anything to do with plot, it has to do with acting, writing, and the bad direction that a movie takes.
Just because there aren't any epic 'scenes' in no way can say that the plot of a movie isn't epic. Dialog, filming, camera angles… none of that has anything to do with plot. Sure, they can make the delivery of a plot bad, but saying that the plot itself was bad due to these flaws in presentation makes you look like you know little about movies.
