Welcome to the Ice Age!
umm i watched it in 3D. it didn't really really impressed me.
i think the 1st and 2nd ice age more funny and better than this.
when i watched it i felt a little bored and sleepy :D
i dunno, maybe it because i slept late the night before so i had not enough time to sleep.
but it was still funny. watch it! maybe you like it :)
