Star Trek WTF?

I started watching TNG again (I last became bored around the begging of season 2). Was this show always like this? or am I just having a lucky streak? (no pun intended).
First of all, counselor troy is a man! In season premiere "The child" (which I've seen before but missed this) she is said to be impregnated by a child made entirely out of her own DNA, but the child turns out to be a boy! (women lack the Y chromosome* and no combination of their DNA can produce a male. Ever.) In "Where Silence has Lease" the omniscient reptile thing looks over the bridge (which has the regular compliment of Crusher, Data, Worf, etc... as well as Troy and Doctor Pulaski) and looking over Pulaski (who is a woman) says "what are you? the construction differs!", it is presumed (out loud, by Data) that he refers to gender. Finally in "The outrageous Okona" Troy is right there on the bridge, Picard consults her while Okona watches, yet when a female officer communicates to the bridge, Okona is surprised: "is that a woman I hear?". I'm telling you he's a drag queen (played by a female actress to confuse us!)
Today I'm watching "Royale", by the time I got to minute 6, Giordy detected a temperature some 18 degrees below absolute zero (-291 Celsius) and Picard sent "a small away team", which contained almost every senior officer on the ship, (except Himself and Giordy) into a potentially extremely deadly environment (the extreme danger is stated in no uncertain terms). When (by minute 8) the away team loses contact with the Enterprise, instead of trying to backtrack Riker just says "were here already, so let's look around", what's up with that?! I've seen porn with better driven plot! And as Data gets new and interesting readings, Riker just walks around and grins, like it's a gosh darned amusement park. (is he high?). Then, when Riker suddenly (!) decides they should go back, the away team fails to operate a revolving door. No, they are not teleported back, they just FAIL. The rest of the comedy is more or less business as usual.
