Saw Hairspray tonight...
Lots of fun dialog and amusing scenes, reminiscent of the fun Broadway musicals of the 50s and 60s. Combined with the fun music and great acting, it came across quite well as a light-hearted view of the racial differences and push for integration in the early 1960s.
I'd give is a very strong B.
Afterwards, I snuck in and watched the 2nd half of Harry Potter. Missed a few of the happenings but found it to be a good continuation of the other films. I still think I would have paid to see it in full, but not sure that it's worth paying to see the first half. Given that, I would probably have given it a ranking of A-, slightly off because some of the scenes seem a bit erratic and hard to follow, but generally very interesting with great graphics.
