If you can't discuss the subject as such and instead has to come up with childish accusations and exaggerations, then I would like to suggest that you simply quit coming up with comments about this.
You say that but you also say this:
And you can't find any actor in this era who could play the characters as good as Stewart, Frakes and the others did.
Which is an exaggeration of the lack of quality in modern acting. Of course a new cast could play the parts just as good, this isn't even a question, recasting characters is normal and should happen more often. No actor owns a character or played them so well that no one can ever do it again.
You also list the CSIs and NCIS as examples of great tv? Like them as much as you want, I certainly have no problem with a well made procedural, they can be fun but they are hardly the pinnacle of tv.
I you don't want a reboot that's fine but maybe don't act like modern tv has nothing to offer, there's so much great stuff out there.
