Objective Homer - and BB himself probably falls into that category
He makes mistakes. He'd be the first to admit that - particularly in the draft, but also in free agency. It's all a crap shoot.
And in terms of BB's success, yes, you can't argue its there - but I think I'll also give Tom Brady a bit of credit for that success as well.
Criticisms of Belichick decisions are often (but not always) valid. But I'll generally assume that Belichick knows a bit more about football and the needs of this team than most fans here.
