Henne has been fine. No reason to put him down, but no reason to pump him up either. Til he gets some consistency catching the ball it's not fair to say we know what he can do.
I know he's got the physical skills - I want to see the smarts. I want to see the little things (like not calling a timeout when you don't have any), reading blitzes and making audibles, etc. It's the stuff that makes the greats great. As ridiculous as it is that we went so long without a QB with a decent enough arm, it's not a big deal to have one.
So far, I like that he's not making huge game-changing mistakes - he's playing smart, if a bit conservatively. But that's what he ought to be doing right now.
