of course I don't agree at all with our friend @Fly_like_a_don because Swimming has offered the audience some of the most exciting moments in the Olympic history...
and if in general liking it or not it's up to personal taste, saying that there's no action it's pure blasphemy...
coming to the quote, I just made a quick research and I found out that in the entire Olympic history (some events were already there in the 1st modern Games, Athens 1896, most of them though are there since 1968 only) there have been very, very few "doubles" between 100m and 200m meters races (and 200m + 400m Freestyle)...
that's the full list:

as you might notice, the only style with a few more doubles is Backstroke (actually 200m and 400m Medley are usually a double for the same athlete, but it's the only exception in the whole individual schedule)...
in a few disciplines, the doubles are almost unheard of...
so, that's the simple demonstration that there's way more diversity than people can even imagine in the current swimming program (which doesn't need too much changes, just add the 50m for Back, Breast and Fly and get rid of the mixed gender relays)...
p.s. and if we eliminate the doubles obtained by the East Germany's girls (you know why) and by the 2 greatest male swimmers ever (Spitz and Phelps, who got the most of them), the list is basically down to a few "white flies" in the whole history of the Olympic Swimming...
so, please...feel free to dislike swimming on personal taste, but stop all the bullshits about the rest...
