I really like the lens flare look? I also like things like CG shots where you see bits of "dust on the lens" and so forth.
It adds another dimension for me.
Yeah. Although, of course, since we're supposed to be omniscient observers, I don't see why they have to treat the camera like there's a real film crew filming the Enterprise. Don't mind it, I just don't think it's more realistic than not, in this particular case.
Well, for the CG shots it's more realistic because no lens is perfect. There will always be some distortion or dust.
And, if you were standing on the bridge of the Enterprise, just looking around, you'd still see lens flares in your eyes depending how close the light source is.
It's supposed ground you in reality and I think it works pretty well.
