On the one hand, an all at once January dump might mean it's terrible.
On the other hand there is nothing else out right now and as we saw with What If, they seem to be experimenting with release schedules.
This "all at once" is similar to the Netflix style, or at least the Daredevil Netflix style.
We're also getting 5 episodes instead of a more standard 6, and each episode is expected to be ~40 minutes. So we're basically just getting a long movie. And to me cutting an episode means they're not trying to stretch things out.
After Secret Invasion my expectations are low, but I really want to see something great since this is basically all we're getting this year.
