Hmm.. honestly.. when I first heard that Viewfinder will have an ANIME/OVA.. I was like "OMFG OMG OMG I AM DYING" something like that. Then someone corrected it and said something like this:
"It's not an anime or OVA. It's an AniMix"
The definition of AniMix in my head is like compilation or MIXTURE of different anime, scenarios, music, etc. So I was a bit disappointed when I learned that it's not an OVA at all. But even so (at that time), I didn't care. As long as I can see Asami and Akihito or even hear their voices, it's alright. But of course I kept reminding myself that I'm not going to expect anything.
So when the AniMix was released last February 29, 2012 (I've watched it last March 1, 2012 though).. I actually enjoyed it.
Story:
The whole episode/movie/AniMix (or whatever it was) consists the following chapters from the manga: You're my Love Prize in Viewfinder, Fixer and Love Prize 01.
It is practically the same with the manga. So no problem with that. (Though I would be more happier if it was the Hong Kong Arc XD)
Characters:
Actually, from my point of view, it really looks like an anime/ova. Though the only problem is the lack of movements. They don't "move" that much. The characters don't blink their eyes (that much I guess) or they have less facial expression. They look stiff. Well it is an AniMix after all so expect that.
The only thing that bothered me was how the other characters (including Feilong) speak Chinese. It was really funny. XD
Enjoyment:
As a Viewfinder fan, I really enjoyed it. I mean.. just hearing the Drama CD made me so happy. What more if I see them moving and talking right? Especially the S&M scene (though nothing graphic). But of course I'm still wishing they will make a "real" anime or OVA of it.
Overall:
I guess I'll give it a 7. I enjoyed it but of course I still prefer the manga. I recommend you to read the manga first if you HAVEN'T READ the manga. Because you will not enjoy it that much.
