Ppl who don't get or hate this movie are probably not the target audience. Or think too highly of themselves. Sometimes ppl only see what they want to see.
What sells this comedy is that it doesn't take itself too seriously; it accepts its role as a frivolous parody of Twilight and similar melodramas and just has fun with it. Adams is excellent as the naïve Davis, who by virtue of some fortuitous food aversions and a timely encounter with body glitter sets the rumor mill in motion about his true identity. Given his social awkwardness, it's hard to blame him for riding the popularity wave at the expense of others' feelings, but it is good to see him step up and do the right thing in the end.
LIAR, LIAR, VAMPIRE is silly and self-effacing, but it does well to illustrate the importance of being yourself and surrounding yourself with people who appreciate the real you. Davis is influenced by his sudden popularity to become someone else just to maintain it, but he learns that that doesn't bring happiness, and Vi finds that there's value in peer relationships with the right people. Even Caitlyn changes for the better, giving tweens three examples of characters choosing integrity over status.
Someone asked if teens can be that stupid? Yes! It's called peer pressure and mob mentality. Most ppl are sheep whether you believe it or not. I love how short, sweet and simple the movie is and not overly complicated for a kids movie.
I esp like the fact that they don't divulge everything. They make you think. Like how Davis and his mom move around a lot but they never reveal her profession. Or how every time they move she gifts him a kaleidoscope. I believe that she may be some kind of scientist or agent for the supernatural and the kaleidoscopes are actually a useful tool in spotting supernatural beings like vampires.
