Bethesda is sub-par in just about every aspect of game development. Shallow combat. Basic dialogue trees. Skill/feats haven't evolved in several games. Engine so old it has to have loading screens for every type of transition.
But you picked the story and acting to tout as good? Bethesda is well-known to have pathetically bad main-story arcs. Only a handful of side quests end up being engaging to most people. The face animations are...better now but still deeply in the uncanny valley. Their acting is usually deadpan with only the merest speck of emotion and shown as if the actor is reading their script for the first time during recording.
Honestly the main thing that Bethesda games have going for them are a detailed, hand-crafted world that is fun to explore and experiment in. Which...Bethesda handily disposed of to have the majority of its world and worlds be procedurally generated.
