I found it hard to review this one. On one hand, it reuses tired old tropes of Star Trek. The theme of humans gaining powers of a god already appears ad nauseum in the Original Series, most notably in Where No Man Has Gone Before, Charlie X, and Plato's Stepchildren.
However, Hide and Q does break new ground, featuring a reluctant Riker being tempted by Q to become just like him. For the most part, it isn't very interesting, apart from the fact that it continues the Q arc, of putting man on trial. Thankfully, Riker is more than up to the task of becoming a foil to Q. However, to be fair, I think Picard would have been a much better choice, since he and Q couldn't be any more different.
