No idea why this doesn't have a higher average rating unless it's because Twilight fans can't take a joke. I, personally, LOVED how the "HollyBlood" movie within this movie pokes fun at the Twilight saga. Especially how it loves shirtless men acting all aggro and buff.
The only thing I loved more than that was Javi's dad, Fernando. The recently divorced dad energy was so well played. His encouragement to Javi, after assuming his son is something other than straight after seeing the HollyBlood site on Javi's laptop, is so funny but also a genuinely endearing attempt to connect and show a child that you love them regardless of their sexuality. Jordi Sánchez acting, his expressions and body language, was just perfect for this story and he absolutely stole the movie for me.
The subplots with Diego, the wannabe vampire hunter, and Carmen, Sara's "disabled" friend are so good that going into any more detail about them would spoil how delightful they were. Isa Montalbán played the character of Sara so well and Óscar Casas was priceless as Javi. The weird little gym teacher and ridiculous dance sequence in gym class was hilarious. The real vampire was good, but that's where the movie starts to plateau for me.
The Manu bully storyline was my least favorite, but teen movies of this sort do always have an obnoxious bully so he serves his purpose well. The ending also falls flat for me. With so many moments that made me laugh out loud throughout the movie, I just think there could have been something more to parody how these teen movies typically end instead of having the exact same kind of cheesy happy ending. The "HollyBlood" fight scene from the movie within the movie was priceless, though.
