That 'something' is the stuff that goes under the radar, the hard yards and simple stuff which will never grab the headlines. I think that's why so many fans criticise him, because they can't see what he brings to the side.
So many fans these days look for the sublime, the moments of magic etc, but the players who give their all, ain't flashy and do the dirty work in the engine room often go unnoticed, to the point that they become disposable in many fans' eyes.
If you take the time to watch Gowser, you can appreciate what he brings to the side. I genuinely think we're a far better side with him playing, as was very apparent under McCann when he either subbed him off (threw it away) or subbed him on (made a fist of it having been pumped all game to that point).
Don't expect most to agree, but that's how I see it.
