I think the show and Next Generation is funny in that people with certain names (ethnic) "look" that ethnicity.
Miles O'brien a white guy with an Irish accent. He should have been say a part black part Asian guy.
Keiko= looks Japanese, maybe she should have been white with red hair.
Nobody has any names from places like Denmark or Sweden. No Lars or Sven.
Ensign Gomez, with Geordie in engineering, she looks like what in the USA is called "Hispanic" today.
All of that bothered me I guess. Too many one "race" humans still, 400 years in the future. With names matching the "race" they appear to look like.
