I would actually give this 2.5 stars - on the basis of
+
Superb graphics and realism
Great score (when it was being played)
Some of the maps were really well planned for interesting combat takes

The plot was not well written in my opinion; I do not mind what happened to the protaganist of the first game, however the way the stories were structured made me hard to care about the playable antangonist; too many coincidental situations made the story unbelievable (esp in contrast to the first game)
Druckmann was trying to weave in many social messages into the game; when gaming is actually a medium of enjoyment for me, the repeated somewhat blunt messages (violence is bad, revenge is bad) can get tiresome especially in game where you slaughter plenty of enemies.
