This cartoon, as learned from the titled of this comment, is the best Superman cartoon ever ("Mechanical Monsters" being a close second). It is very refreshing to see my favorite superhero in a situation where his powers are actually useful -- without inventing any ridiculous, previously unmentioned powers (see "Superman: The Movie" and any episode of the "Superfriends" shows). Basically, a frozen tyrannosaurus rex is accidentally thawed (and obviously misidentified. Whoever labeled this either does not know what a t-rex is, or thinks a t-rex looks a lot like Godzilla), creating panic in Metropolis until Superman shows up and punches it in the neck.
Bottom line: A giant dinosaur getting beaten up by Superman + great animation = BEST SUPERMAN CARTOON EVER.
