It certainly better than it sequel and some have liked it better than the prequels, at least the first prequel. It doesn't help that Scott made the same mistakes that both AVPS did, screwing with the lore and the lifecycle.
AVP=fast alien lifecycle.
Alien covenent - Ultra fast lifecycle.
AVPR - added a new reproduction method that would render previous one obsolete.
Prometheus/Alien Covenent added a biological weapon that would render Alien one obsolete. Also huggers can implant instantly without need of rendering someone comatose, thus making previous iterations obsolete.
