>And somehow people in space with Ozzie accents just doesn't seem right. Well when they've ALL got the accent (and some very annoying versions too), even the mystical goddess blue one (except the misery-ass yank) then, although the it's in the future, it just doesn't lend it verisimilitude somehow.

And all of them having American accents across the board does? :)

Likewise, when all the planets visited have red soil, same vegetation, same master-servant social setups (unless they are a hive mind), all have one religion (or one dominant and the other underground - and none are religion-free)... how's that for plausibility.

Not to mention that in most cases the imagination of the writers ends with aliens' names ending in -on or just adding an apostrophe somewhere in the middle. Too lazy between the ears to use even the usual trick of borrowing simple words from less known languages. I'd just love to see one with names like Bdim, Gde, Knedla, Gnezdo, Pskov, Pshen (no silent consonants) pronounced by Anglophone actors :).
