Reversing things TNG did was the main reason I was compelled by Deep Space Nine, because the crew couldn't rely on what was a staple on TNG. The realization for me was as soon as the Enterprise left the station this new crew was alone. No Klingons, Romulans, or any of the familiar faces I once comfortable in viewing, this crew will have to adjust and becoming some clever chess players because these new villains or adversaries are as interesting and as intelligent as they are. Problem was these adversaries (The Cardassians) had the home field advantage and any slip up -- the mission, and the security of this new world would be in danger, which means reinforcements would take about an Earth week to reach there and that would be too late. The 1st 3 seasons especially the mid-season 1 and the real full season 2 were some compelling television and some of the most interesting character compilations Star Trek has ever done.
All were flushed down the toilet when Ira Behr took over. Everything I found interesting about the show being unique and distant became familiar to what I'd seen already on TNG: Klingons, Romulans, Breen were all back into the fold, the Federation were now closer than ever before, bringing more cliches to the mix they now have another super, major one dimensional villain called the Dominion, the first super bad guy was the Borg, but the fan-wanking didn't end there Ira brought in Worf - one of the most popular characters from TNG, to bait TNG audience to watch which meant viewers could now be more comfortable with the drivel Ira and his team can muster. A complete betrayal of the fine work Michael Pillar developed for that series, having wars and blasting and some times asking Gods to fight battles, and tarnishing potential characters is not the formula for interesting TV, that crap only satisfies viewers' own short attention spans - ones who are and still is accustom to familiarization to what they think of as Star Trek. Ira's claim DS9 was too different for some, he's dumbfoundedly mistaken, his version of the series was drowning with fan service, and was muddled with too many subplots to the point many of them could never be resolved.
