Deep Impact - May 8, 1998
Armageddon - July 1, 1998
The spring and summer of 1998 was a bad time to live on planet Earth. Not one, but two giant meteors were threatening to wipe out all of life as we know it! Fortunately, both Deep Impact and Armageddon focused on one team's efforts to protect the planet from meteors.
Neither film fared all that well with critics - Deep Impact has a middling 47% fresh rating on Rotten Tomatoes, while Armageddon earned an unimpressive 39%. However, both movies were pretty successful financially, with Deep Impact earning about $350 million and Armageddon raking in a whopping $550 million.
So who wins? While Deep Impact is probably the more scientifically accurate movie, Armageddon was a bigger hit and has had more of a cultural impact (plus Bruce Willis), so we're calling this one for Armageddon.
Winner = Armageddon.
