Seems to me that much like when Lukaku arrived at the club with his £28m price tag, there are some (negative) Evertonians who will use the price tag as a stick to beat Bolasie with regardless of whether or not he actually does well for the team.
Clearly he could improve his consistency, but as an inconsistent player he's still proven that he can contribute not only with assists and creating chances, but also with hard work. His tenacity for the goal was great to see and we have benefited from that on a few occasions this season.
He has managed to form an excellent partnership with Lukaku, and sits 2nd in the assist table, whilst also creating numerous other great opportunities that weren't put away by his team mates.
People also need to appreciate that the reason Bolasie (and to an extent Lukaku) play for a club like Everton and not better teams is due to that lack of consistency in their all round performances. For me, they both frustrate at times, but both are contributing in goals and assists at the moment. If Bolasie was capable of improved consistency then I doubt he would be at Everton for long as there would be CL teams in for him given that he's 2nd in the assist table despite having played poorly in parts.
