I just finished it. It was okay, but I don't really understand why they used timetravel like this. I get they might not have known how timetravel works in Endgame on time, but Endgame's timetravel is the same as that in the comics and what Marvel TV also used in AoS (with Deke not disappearing), so I don't get why this show chose to go by different rules suddenly (while also using the Darkhold form AoS). Same with the dimensional stuff. This show seems to completely conflate Dormammu's Dark Dimension with the Darkforce dimension in a way that really doesn't make any sense.
