Snoooooze....
Although, I'll admit, I can see how opinions about this place can be a bit polarized.
If you love memorabilia and are in awe simply to be in the same airspace as some artifact from rock & roll history, this place is for you.
I found myself more interested in the history-type exhibits, but as others have mentioned they were pretty dark, and not easy to read (which was too bad! They looked interesting!)
Also, $22 was a touch shocking, considering the MET costs $20 and is 10x the size.
