Obi-Wan could have killed or disarmed him anywhere in the first two gifs.

And that’s why I’d make a terrible script writer.

There would be no big heroic moments, just sudden death.

Even in the 3rd gif, he is so wide open. Plus Grevious always does wide overly done swings, a quick stab would instantly put him down.

In context, the Jedi are not really given to aggressive swordplay. Kenobi particularly so. 

But in that moment of him spreading his arms with the lightsabres, you could have all four of his arms off, then his legs, then slice the full length of his body. 

Don’t be so harsh on Obi, the man is looking at a green nothing for the length of three gifs here.

If you guys are going to argue about how “he could have killed him during this display” then I bet you’re the same kind of people wondering why the jedi don’t just sneak into places and stab people in the back without alerting them, or why the jedi don’t just mind control all their enemies to shoot themselves in the head; and you people are also the ones who completely miss the entire point of the jedi and how they are different from the sith.

if flaws is all you seek, flaws is all you find. i dunno how ppl can enjoy anything ever with that kind of mentality. just circles of pure uncondensed hatred and misery.

I pity people who are unable to enjoy anything ever and only can feel/seek out the bad things in life.

Hell, Grevious was probably standing there the entire time thinking “Go on, attack me, do it jedi, surprise me, just this once, and attack me before I attack you. Do it. Bah, thought so.”

He’s supposed to be a cyborg that is more machine then living person at that point. He is supposed to have the reflexes and speed to intercept such a blow. That said he is also set up as a Jedi slayer who killed many Jedi up that point - of whom also are some quiet famous an well known among these.

The only reason he evtl lost to obi is because he got badly damaged just prior to the third movie - at the assault at the imperial sense when they kidnapped palp - there he got (ironic) gravely wounded in his chest area - lungs/heart etc took a bad strike and got literally crippled (without repair he was slowly dying hence him constantly running away in the 3rd movie)

(This is mostly a fan theory but based heavily on facts we got presented with over the time through the clone wars cartoon movie for example and others…)

Also those big flashy swings are key to beating a Jedi. They’re all about discipline and control and his weird jank is used to mess with their heads and keep them distracted and be intimidating.
