I don't what you other guys are complaining about, but Bashir turning out to be genetically engineered was the best thing that could have happened to the character. Suddenly he became distinctive, and a candidate for the forthcoming Section 31 plots (and Inter Arma Enim Silent Leges
is one of the most coolest, cleverest and complicated episodes ever!). Without this Bashir would have been another Harry Kim, always there but never really standing out.
At last Bashir is standing out, plus his parents were cool, I love Bashir's father's English accent. For the most part this revelation about Bashir being genetically engineered fits rather decently with all the development and characteristics of his character.
