Who gives a flying fuck?
Funny you should say that.
I remember watching Terminator 2 when it was first released and thinking "how did they do that?"
Same for R2D2.
But I can hand on heart say, that as much as I enjoyed Ted the first 2 times I watched it - I never paid a thought to how they did it.
In fact, just like you say, I couldn't give a fuck.
