Easy, you should watch TOS *first*, and then complain about inconsistencies 
that TNG era Trek introduces 
1) Why they look weird:
       Watch "Trials and Tribble-ations"  for Worf's explaination.
  A) Simple answer - they didn't have the money to make them look good
                       (That's why they used Klingons, because Romulans were
                       too expensive)
  B) Better Trek answer - they used cosmetic surgery because they did not
                       think that the humans were honourable enough to be
                       honoured with their true appearance.
                       (We know that they have the ability to do great
                       plastic surgery because of Darvin the Klingon
                       in human-form)
  C) the wrong answer - they're human/klingon hybrids, or another race of
                       Klingon, not the Imperial Klingons of the
                       bumpy foreheads.
               Why this is wrong: Three klingons from TOS showed up on DSN
                               They looked exactly like every other klingon
                               in TNG era.
  D) the other answer - something horrible occured between TOS and ST1 to
                       the Klingons. This brought about changes to all
                       Klingons. (This is why Kahless looks different in
                       TOS and TNG)
As to honour:
      A) simple answer - Roddenberry didn't like the portrait of the
                       Klingons from TOS, because they were "all evil", so
                       he added better qualities.
      B) better Trek answer - The Klingons did not think the Earther scum
                               were good enough for honour. They changed
                               their mind later.
               Why this is wrong: Kahless in TOS is different from the
                               Kahless of TNG.
