I do think he gets way too much flack. I don't think he's the problem with BOTS, I actually think he's not that bad at all. It's the production of BOTS which is why it sucks, not the presenter (Rylan).
The only issue I have with Rylan is him appearing in the adverts every series. I don't remember Dermot or Russell being in the C4 Adverts, but then again C4 trailers are different to C5. But I'd prefer if it was just Emma in the adverts, like the Secrets and Lies advert
