When there's no more room in Hell, the dead will walk the earth. 

Admittedly, this film takes a while to pick up but once it does, it's a good ride.  Imagine having an entire mall all to yourself, things would seem awesome despite the chaos and death going on in the outside world.  The people in this film had it so good in the mall that they even started watering plants, ice skating and having fancy dinners while people on the outside were being mauled and eaten alive.  NBD.  That is until a jealousy filled group of assholes on bikes showed up and destroyed what took the main characters so long to build.   They started breaking doors down and looting as if they could go on the outside and pawn jewelry and glassware for supplies. the only redeeming quality about this group of miscreants was that they threw pies in the zombies' faces and that was hilarious.  Overall, this film touche don consumer culture and greed and what idiots humans can be when they're in large groups and Steven, poor Steven.  After all the events that take place and getting to know the characters, I am just glad this film ends better for the protagonists than its prequel did.  Those pies though lolz.
