Since its debut in 1993, The X-Files has become one of the best sci-fi shows on television. The original series ran until 2002 but was revived for an additional two seasons, totaling an impressive 11 seasons and 218 episodes. The X-Files follows two FBI Special Agents, Fox Mulder (David Duchovny) and Dana Scully (Gillian Anderson), who investigate — yep, you guessed it — the “X-Files”, a string of unsolved cases featuring alleged supernatural phenomena.
