This season, BBC America is pulling the same frustrating trick it did a few years ago: moving around one of its best programs, The Graham Norton Show, so that it’s almost impossible to find it. Like Orphan Black, this show, too, has moved from Saturdays to Thursdays – but in this case, not only outside of prime time, but delayed until after After the Black. This talk show series, imported a few days after it premieres in the U.K., ought to be seen in prime time. It’s that good.
