I learned long ago to ignore such things and just immerse into the fantasy. Watching a movie or just about any other type of show- unless it's a documentary- is pretty much an escape into fantasy. Why ruin it? They don't care what you think. If you can't help dissecting it, stick to documentaries and such. Or, maybe you are getting your enjoyment from the critiquing process. Meh.
P.S. I really, really want my own Iron Man suit!!!
