Louis Walsh: Thoughts?

A new Boyzone documentary comes out on Sky in a few weeks, and in the promo adverts for it, Louis Walsh comes across as an odious, little bastard. This has always been my default opinion on him, from seeing him on other shows, or reading about how he ‘managed’ other bands. He made millions off the hard work of those he should have treated better. Is he the absolute c*nt I think he is, or am I missing something?
