Interesting article, Paul.
I still enjoy the production shows, though I must say i usually have to drag Art. Best one I've seen so far is on Star Princess due to the incredible stage that allows scenery and people to fly in and out, and sink below stage.
I will also always hit the comedians (especially the R ones). Always makes for an enjoyable end of the day.
The shows are always one of the best parts of the cruise for me -- how often do I get to "go out" every night, other than a cruise.
