WTF? I completely disagree; ST:TNG (and TOS) is a breath of fresh air compared to modern TV. No over-the-top ultra-violence, no half-second-long Michael Bay-style shots, no requirement that you've followed the series religiously and are watching the episodes in order; it's a great way to relax and watch something enjoyable. It's also nice that all the characters are hyper-competent; this is a nice break from the real world which is full of incompetent morons. If I want to see "dark, gritty realism", I'll go walk around a ghetto or something.
For example, there is this one episode that develops a bit strange. Piccard shouts "shut up Weasley" and blindly ignore the fact that Data is acting weird. Of course that's the plot, but I don't find it convincing.
Also, the episode Hide and Q (I like Q character), it's a bit trivial in script writing compared to today understanding. However, Q comes back at the end of the next generation and make a profound appearance (he puts Piccard on a trial because he is interested in Piccard as a superior human which is a nice thing because he and the Q continuum regards publicly human as an inferior species).
I just say that there is "some" plot holes but overall, it's still something I'd stick to.
