These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
YMMV: The Infinity Gauntlet
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 - don't worry he gets better after things like House of M and Avengers Vs. X-Men.
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.
Villain Sue: Thanos has been considered as such by some fans, since he is basically unstoppable for most of Infinity Gauntlet. Justified in that he is using an artifact making him omnipotent; anyone would be invincible in this situation, as Thanos himself mentions when Nebula gets her hands on it.
It was only a matter of time before Nebula gained the upper hand. She possesses the Power Infinite. With such might, any dullard would eventually prove victorious.
