With in the first 10 minutes of watching Enterprise, The next (or first?) series in the Star Trek saga, I noticed a serious flaw in the timeline of events. Mainly, the appearance of the Klingon warrior. Going back to an episode of Deep Space 9 (When they went back in time and prevented a modern-time Klingon from altering history) Wharf explains (brielfy) that an Accident occurred that changed the appearance of Klingons from what they looked like in The Original Series (TOS) and what they look like in the later episodes (DS9, TNG, etc…)
Since Enterprise takes place before TOS, the Klingons should appear like they did in the Original Series and NOT like they do in the modern series!
