||The playful, all-powerful being has been done to death now, but it must have seemed a lot fresher back in the day. Gene Rodenberry must have been thinking of Trelane when he came up with Q, so the two are linked, at least in thought. William Campbell's version was certainly effective on first viewing, and a bit disturbing. Perhaps it's rubbed off with time, but he seems to have lost it a little. We had another 'Rand stand-in' in Yeoman Ross, who once again ended up as a passive character, but contributed a little. The date this is set was a bit confusing, but I don't think they pinned down any date at all until well after this was made (compare with "Space Seed" for instance). Certainly a decent episode, but don't watch it too much.
