In uncanny avengers #9 they show 4 bodies to whom are given 4 death seeds, but Sentry's body burned in the sun. Is it bad writing or there is an answer to that? To me it seems such an huge mistake that there must be some reason.
Other than that, do you think the void will overcome the death seed and the sentry will go out of control?
There is also a physical mistake (there are lots of them in comics, but it is funny to point out): wolverine heard a sonic boom hundred of miles away, and before he could react sentry made his appearance. Sound's speed is about 300 m/s, so sentry should have come way before wolverine could have noticed anything.
