Vampire Dad is not a great movie. The script is not tight. The movie feels like the writer ran out of ideas and needed to pad it out to get it to about 76 minutes. This sounds pretty negative, BUT I will also say this movie made me laugh HARD many times, usually due to Barak Hardley's performance as Bob. So although I cannot say this is a great movie, it's hilarious at times.
The performances of the leads are very strong--Emily O'Brien and Jackson Hurst are fantastic and have wonderful chemistry with each other. The set designer did a great job--I particularly noticed the use of vibrant colors to suggest the era. There's a kickass surf rock soundtrack by Voodoo Surfers.
I did not love the use of animated segments--I wondered if perhaps those were added because it was easier than building sets or finding locations for those scenes.
I agree that the movie never quite does what it needs to do to capitalize on its premise. What it does have in spades is charm. I do hope they'll do something more with this cast.
This is not a movie anyone needs to see, but I had a good time and you could do a whole lot worse.
