Broken Base: There's a lot of disagreement on whether Infinity War and Infinity Crusade are good sequels to Infinity Gauntlet or not.
Harsher in Hindsight: It's really hard not to wince at seeing Cyclops fighting alongside the Scarlet Witch and Captain America coming to his side when he's seemingly killed after things like House of M and Avengers Vs. X-Men.
Misaimed Fandom: Infinity Gauntlet is often seen as an epic Avengers crossover where they take down a super powered baddie. Gauntlet is actually more like a Thanos and Adam Warlock story where the actual Avengers are little more than a Red Shirt Army who gets easily dispatched in creative manners by Thanos with the powers of the Infinity Gems, and the story boils down to Thanos realizing that his attempts at getting Mistress Death to love him where All for Nothing and that his previous defeats were caused by his subconscious feeling that he doesn't deserve all that power. With that said, the Avengers still get a few awesome moments like Captain America confronting Thanos as the last man standing.
Signature Scene: Thanos snapping his fingers to make 50% of the universe's population disappear.
Tough Act to Follow: Jim Starlin has every cosmic book given to him compared to Infinity Gauntlet. His later work is rarely compared to the original series in a favorable light.
