These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
Internet Backdraft: So far, a ton of videos on YouTube of him have fallen under this. It's best to say that quoting anything from Portal 2 is bound to start a flame war.
Likewise, simply mentioning you liked him as Wheatley is enough to warrant flames from fans that have known about him from hisearlierworks.
The Woobie: You'd think he gets rejected by every woman he talks to, the poor guy. But YOU would never break his heart like that, would you? No, you'd hold him and just kiss all that insecurity right out of him.
The really confusing part is that the guy has fangirls, and he's still single. The question of how comes to mind.
There's also the matter of his sitcom getting cancelled after one season. Pretty rough considering this was his first real attempt at escaping Ricky Gervais' shadow.
