Not really a surprise or a shock imo.
DH Aliens comics were one of the few things I ever "collected" as a kid, as I own every single issue of the series, some in multiple forms and collections. But lets not pretend that lots of early Aliens stuff was a) more than pg13 and b) any good. Plenty of trash tales in the series and revisionist glasses do make things look better.
I remember several posters that have posted in this thread trashing the dh series five or six years ago.
You will get more of the same and you will get them with more frequency and more consistently good, if formulatic tales.
If they can't make any money off of it, then it will go somewhere else. I don't see most Marvelites wanting the Aliens series because they can't argue over which alien has god tier abilities and which one doesnt.
I'm suspecting Marvel is wanting to try their hand at more mature writing sometime soonish anyways, as they have collected too many titles with R rating (including reacquiring their own netflix series) to not test the waters in that regard.
But whatever, the house of Mouse strikes again, we will have to see if Punisher vs the Aliens is any good or not.
Tristian should just basically take what he loves about the Alien, make a knockoff creature, and write (or colab) his own storyline taking his maybe aliens in the direction he wants them to go in. I'm sure DH would love to have something to fill the void.
