I picked up #4 last week. Was ok, nothing too special. I'm going to wait to judge the whole though, when all the series' are out and we see the big picture. I still hate the artwork in the Aliens run though. Really struggle with it. So glad Thies is back for the next run.
The story is just what you would expect. That being said, what we see of the fight between the queen and the Engineer was very cool. I'm looking forward to the AVP series. It will be good to have Ahab back in a larger role.
Just because I don't include it in what 'I' favour as continuity does not me I don't like it. I think it's weaker than other entries to the AVP universe as a whole so far but I am enjoying it. Same as I enjoyed 'Fire and Stone' enough to Buy the Hardcover edition.
