I recently rewatched High School Musical 2. I had forgotten that the movie ends with the villains being redeemed and becoming friends with everyone else, because the third movie pretends that didn't happen. They go right back to being villains. This is especially unfortunate for the male villain, because he had decided to stand up for himself and never be bossed around again. He instantly goes back to doing whatever his sister says.
I also forgot that there are some half-flirty scenes between the male villain and the hero's girlfriend. Why didn't they develop that into a subplot? It had the potential to be more interesting than half the movie.
In case you were wondering, the baseball song is still awful. Whoever choreographed the song clearly has no idea how baseball works. Players don't hold baseball bats like that, no player would bunt with the bases loaded, and the "home run hit" was really an easy infield out. Sure, it's technically possible those plays worked the way the dance number showed, but that would require multiple errors from the team on the field.
Zac Efron has Justin Bieber hair throughout the entire movie, which is interesting, because the High School Musical series predates Justin's career. My YouTube channel does, too. Gosh, High School Musical and I are older than I thought...
