My problem with all three specials is that Scream isn't as represented as much as I'd like but that was a neat wrap up for The Dracula File. I really liked the art style they used in the 2017 special. It's a shame they didn't return to that but to get an actual ending was nice.
I'm a sucker for Kek-W stuff so I really enjoyed Black Max but like Bear says, the schedule didn't help it at all. The art was great and Kek did well but this is one series I'd like to see get a bit more space.
I didn't much care for Black Beth in the 88 Scream special and it was worse now, especially with that art. It's just not for me.
Thief of Senses was a mess. The set up was slow and a bit dull and the ending was really poorly put together with some poorly put together panels. There's a seed of a good idea there though.
The Aegis One for the kids. Didn't care for it much.
Bumps in the Night had a Ghastly Tale feel to it. Artwork was good but the story wasn't up to much.
It's nice to see them keep the Scream! name alive but I don't think these crossovers have been great.
