He's funny, super skilled, mad confident, and actually very kind & caring when he's not playing up the cantankerous persona (see him dealing with kids on Master Chef Jr. for a good example of this). Yeah I love watching him let loose on assholes but I've also learned a lot from watching him cook. Most of the recipes I attempt for the first time, I'll first check to see if there's a Youtube video of Ramsay making it.
