Is this the best vampire movie you're ever going to watch? Probably not.
Is it the best BL movie you're ever going to see? If you only watch pretty bad ones or average ones, then yes, this one's certainly not bad - but I'm not going to claim it's the best one out there.
Does this movie have the greatest special effects in the world? Absolutely not. Far from it, actually. The effects were meh to just plain ol' bad. It's obvious that they didn't have the biggest budget for the CGI, but they worked with what they had and it worked out okay.
There are some things this movie does do very well which make it a very enjoyable watch. The story, for one, is rather original and throughout the movie, they just keep throwing new stuff at you so it doesn't get boring at all. Whenever I thought, "Ah, this is getting a bit bland...", the movie was like *Bam! More plot!* (and by plot, I mean actual plot... and also really great BL scenes if you can find the uncut version).
The chemistry between our main characters was also pretty great. Like I said, if you manage to find the uncut version or you watch the cut version and find the cut scenes online (I found some on facebook of all places!) and watch them at roughly the right moment, your itching for BL will be scratched. There was a lot of wholesome and unwholesome content. Bless the creators and actors, seriously.
Overall, I can honestly say that it was a good movie, not the best, but good enough. Original, great chemistry, music was okay (in the version I watched, the sound kind of faded in and out of existence so I couldn't really pay it that much attention), try to find the uncut version!
