Quite honestly, those dozens that rate it a "1" and repeatedly state its boring are simply not capable of higher thought and just don't get it. Plus they are either a bunch a of adolescents or have yet to move out of their parent's basement.
If you watched this trilogy and expected a Hollywood-ized giant slugfest you will be disappointed. But if you paid attention at all during the first 2 installments, you'll get it as the end of a story-arc.
