In the Stargate SG-1 episode, "Window of Opportunity," Colonel Jack O'Neill and Teal'c become trapped in a time loop and must relive the same 10 hour period repeatedly. During the episode, Jack attempts to record the events of a previous loop, which is a bit odd given his intelligence. Joseph Mallozzi, the writer and producer of the show and creator of Dark Matter, adds a humorous element to the episode by having Jack name drop the movie Groundhog Day. Daniel Jackson is also featured in this episode, although he is portrayed as being quite clueless when it comes to interacting with the increasingly agitated people around him.
The episode is able to deliver a comedic experience while also providing viewers with emotional moments. Jack's attempt to record the events of a previous loop is a bit far-fetched, however Mallozzi adds a joke that only those familiar with his work would understand. Daniel's cluelessness is also comical, but serves the purpose of showing how unaware he is of the situation going on around him.
The episode was rated 8,54 from 684 votes.
