Worst Best Friend Ever
Seriously, Amy as a best friend is a real downer. Her cynical comments about how no boyfriends can be grown up, etc. smacks of jealousy. And she is no real support after that horrendous shower thrown by the wicked stepmother.
As best friends go, I would want the one in "Bed of Roses" or even Rosie O'Donnell in "Sleepless in Seattle." I can think of 101 better best friends than this one.
Poor Rose. Crazy sister and bitter best friend. Amazing that she lives happily ever after in the end.
