Having seen the various previews of DISCOVERY, I couldn't take it seriously as being set in the 'prime timeline' as a precursor to the classic TOS show - and having seen the first 3 episodes now, my view on that hasn't changed one jot! Let's be honest here, it's a complete re-imagining of the original concept by the makers, where very little meshes with the original show's material or tone...
However...rather than look on this as a completely rebooted version of original Star Trek era, I went into it imagining it as an unrelated, 'Alternative Universe' to the 'prime timeline' version instead - and was actually able to enjoy it much more this way!
I still find the opening credits and theme a major disappointment - hell, I'd rather just shorten them to start at the point where we just see the words 'Star Trek Discovery', along with the brief cue of the line drawing of the ship flying towards us, before continuing with the episodes - but by totally separating this from being an actual prequel to the original Star Trek show, I'm now looking forward to whatever comes next...as it won't matter if anything ties in logically with the look of the classic show or not, regarding 'Klingons' or whatever else!
