Although Josh isn't a bad person, he just lacked any sort of self awareness similar to raj, His performance especially in S17 was poor.
Everything about this guy was just off putting even he way he walks all calm and slowly was just annoying to watch.
He ignored any sort of criticism and advice, then would mess up and then act like the victim when his team would get mad this was the case with him putting cold coal on to the fire and then acts like why everyone hates me. Aside from Elise, the majority of the team tried to help in some way especially Manda but she was met with hostility in return and poor performance by him. Michelle gave solid advice to him and all he did was dismiss her completely. Very similar to Raj.
His cooking was also really poor, couldn't even do the frying correctly.
And then the iconic elimination, he came back after multiple mistakes asking for another chance but I think just like Raj, GR just was tired. He lacked self awareness, skill and overall was a really poor team player.
