I watched Romulus one day after my country's (HU) release day, but have joined the fandom just recently. As for the movie, well, the ending sucked. At least in my oppinion. It mostly is because I was always against the idea of human-xeno hybrids.
As someone who finished Aliens: Fireteam Elite I think there would be more than enough variants (Monica for example) that they could have integrated into the movie rather than comming up with...wathever the offspring was.
What about you guys? You think it was a good idea or another xeno variant would have been a better idea (if so, what variant you guys want to see on screen?)?
