Points to ponder

here i am, sitting down with my son, and he's watching Power Rangers yet again. And I made a few astute observations..

1. Why does the blue ninja storm ranger (girl) have a skirt on her costume?
2. It's always the Savage Slash (in Power Rangers Wild Force) that destroys the monster.. so why not right at the start of the fight, just bukak that power lah...no need to fight so long, then like wanna die, wanna die, then last minute only bukak the Savage Slash... reminds me of Ultraman
3. Why do the rangers all jump up and face the opposite direction after whacking the monster with the Savage Slash? What if the monster doesn't die? A bit stupid...
