Thanks Matt.  Couldn't access that for some reason.  Looks like they had a good opening day, not the best, but solid.

In NY, a lot of kids are taking the dreaded Regents exams or other finals this week, and still have school next week.  That probably has some effect. Look for a huge weekend.

I thought Batman 1989 was fairly excellent, so hearing reviews like "best of the series" is getting me worked up.

Saturday can't get here quickly enough.
