It all depends for me. I expect more from a Final Fantasy or JRPG, but any other genre my expectations for narrative are pretty much non-existent. Video games are based on gameplay first so I can enjoy it despite not having a good story or one at all and millions have considering there were like no narrative driven games when the industry started. Bayonetta 2's writing and acting is pretty damn bad, but hot damn is that game designed perfectly. The level design is on point, it flows wonderfully, the battle system is deep and there's plenty of content to keep you occupied.
