this pokemon movie acctually reveals two legendary creatures for battle: the rare creature unknown, plus the ultimate legendary dog: Entei himself!
The advantages are that: one of the most ultimate battle showdowns appears; Ash`s disobedient Charizard versus one of the greatest legendarys ever to walk the earth! this gets suspenseive tension, with a great mini-movie at the start!
the only disadvantage is that it drags on.
