Recent movies that seemed relatively indoctrination-free and were fun:
Despicable Me 2 (very funny)
Rise of the Guardians
Recent movies that are heavily liberalized:
Escape From Earth
Fun Size (not really appropriate for kids or pre-teens at all, but is marketed and billed as a kids' movie)
Beautiful Creatures (again, more for older teens, but marketed to the Twilight age-group)
A fun movie that I've had mixed feelings about is The Croods, not because it is overtly liberalized but because I think that the cautious conservatism of the namesake family is meant as a caricature of conservatism. Your kids are more likely to get out of it a celebration of individual innovation, but the filmmakers seem to mean it as an allegory of "coming around," "evolving" views, and getting over conservative "phobias" and prejudices.
