My adrenaline is rushing, I'm hooked and I see the entire team making the ultimate sacrifice. No way, I say. A story where the heroes ARE heroes and give their all, truly, their all for the sake of the planet. Not possible!
It wasn't. Happy endings all around. Everyone back from the dead. An ending fit for a Marvel Comics sort of epic saga.
An EPIC hero story is always better with the hero dying or being so totally messed up at the end of the "great deed" that the hero is a shadow of its former self. Greek history is full of the mightiest of heroes. Guess what they have in common? Achilles (Dead), Hector (Dead), Heracles aka Hercules (DEAD and then became a god), Jason (disgraced and dead), Bellerophorn ( blind and miserable), etc. I could go on, but I think I made my point.
The ending of this series builds to a crescendo but ends in a happy giggling squeak.
