Here is a review that I more or less completely agree with. If I had the time, capacity, and inclination to write a proper review of Across the Universe, this would probably be somewhat close to it. Okay, thanks, bye.

(My writer's conscience is assuaged, a bit, i.e., I don't know how to write reviews well, at the moment, I am so sorry, dear readers; here, look at something better.)
