Well, of course, the original game was superficial, but the character outgrew that, because of her popularity. :) Photogenic, yes, but an entire history was grown up around her, to explain their origins and what shaped her into who she became.

There's an excellent first draft of an alternative script for the film, which was done in 1997 or something. It's just the initial part of it, but starts out with how her parents died in the plane crash, she was forced to be a survivor and all the rest of it. I'm actually one of the few who was entertained by the film, such as it was, but still lamented it, because of how very superior a 'true' version could have been. They had the budget and the studio massively supported it. It easily could have been what most hoped for, but ended up completely different.

I have not personally seen the 'Bloodrayne' film, but have specifically avoided, because of seeing all the reviews and knowing that it literally turns the character into something completely different: They changed her from a snarky anti-heroine, just before World War Two, to a sympathetic girl in the Dark Ages.

I guess that it all comes down to the feeling you get of being disappointed by squandered potential! You ask yourself, what was the point in all that money being spent to secure the licence for an artistic property, if they're not going to do it justice? It's like seeing an old friend's name tarnished, for no apparent reason.

On the other hand, there are times when there can be too much attention to authenticity and the product can then suffer as a result. The new version of 'King Kong' is a case in point.
