I got free passes to an early screening of this movie and brought my three boys - 8, 7 and 14 - to the showing. I enjoyed it and laughed more than a few times - which is all I really ask for when I see a animated movies (sans some special movies). It was not as good as the first one but it was very enjoyable.
I am biased though as I am a HUGE minion fan. I laughed every time they were on screen. Whoever came up with these guys and their voices are geniuses. I would gladly lay down money to see a whole minion movie.
Bottom line- if you like1 and/or the minions this is a must see. If you did not or do not like the minions the stay away.
EDIT: Crap, forgot an icon. Can somebody with the power to please throw the Lost icon up? This was apparantly shown at Comic Con. It for a station called The Orchid which seems to have something to do with mammalian genetic engineering type stuff. Dr.
