Just because it features characters having feelings, talking to one another, and generally behaving vaguely like human beings doesn't mean it isn't sci-fi. Although you could be forgiven for thinking so.
lol
Sure, but there's been great Sci-Fi where the characters talk to each other and act like human beings. Take Farscape.....the relationship between John and Aeryn is a very good example of how a romance with all it's ups and downs can be portrayed in a Sci-Fi story/setting.
With Eternal Mind (which I really enjoyed, by the way) was set in our current time and place with our current level of technology with the one exception being the "forgetting machine". The only reason they even had any sci-fi elements at all in the first place was because they wanted to tell a romantic story about what it would be like if you could voluntarily forget the person you used to love so much. Solution: Invent dues ex machine to enable the actual story to be told, none of which is really concerned with the technology or setting they're in. It's a great idea for a story, but it could have just as easily been a pill, hypnosis or eve amnesia or something. While the machine did play an important part in allowing the story to be told, it was not central to the story by any means.
I think most good Sci-Fi requires the technology and setting to be significantly different than our own and I just never felt like the world they were living in was really any different than the one I'm living in.
Someone else mentioned how inception was different......for me it was hugely different in that the technology used played such a central part in the actual story itself and was so far removed from anything that we currently have that it clearly belongs in the Sci-Fi genre.
I dunno......could just be me, but if I were online renting the movie I sure wouldn't think to look under "Sci-Fi" for Eternal Mind......Drama....sure........romance or even comedy.....sure, in a million years I wouldn't think to look under "Sci-Fi" for it.
