"It Might Get Loud": Any good?

Somehow, I got confused and I thought that the movie would be on the big screen, beginning mid January. Dunno why.
At any rate, how is it? Is it worth the One Dollar it will cost me from Redbox?

Previous thread on the movie, including a review by WordMan

Well…alrighty, then!

I had to fly across the country on a business trip a few weeks ago and this was the film they showed inflight - I thought that was cool on United Airlines’ part. And I loved the movie.

My work here is done (thanks squeegee!).
