Yes, and isn’t that the point? It’s like saying Thanos is so powerful, how could the Avengers ever stand a chance against him?Also, just to check, isn't Sentry basically in the Hulk or Thor's tier in the comics? Or even higher? So if Sentry is meant to be the antagonist for this film, how are these guys supposed to be able to do anything to him? Maybe they disable him through his agoraphobia?
Also, the MCU essentially defanged both Thor and Hulk, so I imagine The Sentry also won’t be the near-cosmic level threat he is usually portrayed as in the comics.
