This does bother me, that writers do not understand just how vast a universe they are trying to paint. On ONE decently populated planet (Earth), there are too many factions to count, untold amounts of and types of culture, thousands of languages, beliefs, ways of life! Then they go on to make each planet the equivalent of a nation, rather than a world. Another thing about scale is how impossible it would make an interstellar empire; vast travel times combined with an impossibly small invasion force (it would take MILLIONS of soldiers to conquer a planet effectively). Also, the eerily similar bipedal aliens bug me. They just aren't likely to look that way.
I've also yet to see one story that handles space combat with strict realism. I imagine it to be akin to flying a hypersonic submarine with 6 degrees of freedom in an infinitely vast void trying to hit tiny flecks 100,000 miles away. No windows, just 3 or 4 guys jammed into a cockpit that would comfortably fit 1, with a dozen computer screen and millions of buttons. Also, it would, unfortunately, be boring. It would take far longer between passes as speed increases (look at the advances in aeronautical warfare. WW1 has close in dogfights being fought within 100 feet of eachother, nowadays we are shooting missiles up to 100 miles away, sans visual contact.), and you'd be entirely screwed in the case that you ARE hit.
