There's something about an alternate timeline plot that fans of "Stargate SG-1" absolutely love. The season 3 episode "Point of View" is a fan-favorite installment that currently sits at number 32 on the IMDb list of episodes (as opposed to "Emancipation," which IMDb users voted the very worst episode of "SG1") and is fondly remembered for its unique storyline that saw alternate versions of Amanda Tapper's Dr. Samantha Carter and Jay Acovone's Major Charles Kawalsky travel to the main universe to seek help from the SG-1 crew.
"Point of View" was the second time "SG-1" explored parallel universes (the first being season 1's "There But For The Grace of God," in which the Quantum Mirror is introduced). The writers would return to the concept of alternate timelines in the fourth and fifth season of the show, with "2010," and "2001" respectively -- both of which have also gone down as fan-favorites, though we never got a third Aschen episode of "SG-1," which would have continued the storyline from those beloved installments. But there's something particularly impressive about "Point of View," which served as the sixth episode of "SG-1" season 3 and the 50th episode overall, in that the writers actually created the entire storyline in the span of about 48 hours.
