Playing with form or genre can be risky for the audience because it could throw the audience off guard from what they were expecting. One example I can think of when thinking about this is when this season Penn State was hyped up to being one of the best football teams this season which ended up horribly as they had to fire their head coach and having one of the worst records in their conference.
Great example they are performing so poorly at the moment and the coach was not a good fit for the team.
