It is bad. I walked away from it over ... and over ... and over. Whereas tolerable entertainment might be, say, Tongan-style kitsch (like, a group of Tongans dressed in charming native garb and swaying charming traditional dances, in front of Carnival Line cruise boat tourists), the British counterpart of such kitsch ... which was the opening ceremonies ... was bad, awful. The least example is the last time I walked away. It was the so-called comedian who played some of the keyboards in the Chariots of Fire music ... he was not funny. Bad, bad, bad.
But, everything worthwhile is at the end, with the parade of athletes by nation.
