Alot of previous winners haven’t had mainstream apeal. Some odd acts have done rather well. I suspect that he didn’t have the support he needed from the BBC or the prep work needed for a performance. He made his own set witch is typical Sam. He should have outsourced more to other people so he could control the overall picture and so he wasn’t fixing the set before he got on stage. The fact that he was on his own after a performance was indicative of what support he was getting.
