the animation could be salvageable because it's a pilot, but the writing of the characters, really?, you made Van Helsing a bisexual-brony? what's wrong with you?.
The idea of a Van Helsing series maybe good, but you fucked up making yourself the character, what are you, fourteen years old?, you think you're bisexual?, grow up, dude.
now, a constructive criticism, learn how to write, and i don't mean how to write english, i mean, how to write characters (and if you think you already know, i have bad news for you), stop making yourself the main character, give them a personality, that's what a pilot is for, not only say that they're "alone".
Think about it, try to improve.
