This was a mixed bag, but I think overall worth checking out. I picked it up just because of Gwenpool, and I liked her story. Doom's worked for me, as did Rocket's, X-23, and, to a lesser degree, Black Panther's. The one I felt worked surprisingly well was the Punisher, as honestly, he's a murder machine and so why wouldn't he do well with Venom?
What didn't work for me at all was Old Man Logan's, probably because I don't know nor am I interested in that version of the character, and the Host Rider, largely because a lot of that issue wasn't even about him, just this evil scientist guy I've never heard of (who I'm sure has a long, complicated backstory, because comics), plus the art was a bit confusing.
I also wasn't much into Deadpool's story, as it was just too gross and he wasn't at his, well, Deadpool-iest. It wasn't awful, but again, gross.
Overall, this did make me curious enough to pick up a copy of Venomverse, so mission accomplished. It could have been better, but there were some decent intros in it.
