Thumbs up.
This is a long flash video (+) which has a plot of a common vampire movie (+), good jokes inserted (+), not so bad (and sometimes good) backgrounds (+), cool drawn characters (+), talking horse (+), crazy charismatic half-assed vampires (+), average-joe-style heroes (+) and girl companions (+).
Oh, and awesome after-credits (+).
That's 10 + (or stars) for you :).
Of course I was kidding and I did this "rating" for fun, you cannot review a movie like that (although some people do), but I really enjoyed the gloomy comedy atmosphere and characters, and voices were awesome.
I am not a native english speaker so I missed some tiny parts, so could you please make an option to ALWAYS show subtitles (like when that horse-man talked). Thank you :).
