Sometimes I forget it's him. I just always view him as a comedic actor. But yeah, his character is mean as ****.

Very much so

He kind of plays it the same way he plays all of his characters.

I agree he was tremendous. I think he gives one of the best performances ever in a Star Trek movie; for example, folks, check this, remember his read of the line "Yes! It's exhilerating isn't it!"

Christopher Lloyd was great despite having the similar mannerisms of reverend Jim from taxi in terms of the speaking voice.

I thought he was great.
I guess he was a letdown after Montalban, but no one could have topped that. As far as Klingons go, he was a great villain.

He was great. I've always thought of him as one of the smartest Klingons. He might not have the brawn of the others, but he's managed to get to the position he's in with his cunning and smarts.

Yeah I just loved his line delivery.
Lose the Game!!!!!!!

I could not take the Klingons seriously until Star Trek VI -
In the 60's shows they looked like Indian dudes with goatees
Also they speak alot of english and not klingon amoung themselves in this

I for one thought Christopher Lloyd's performance was outstanding. He was a great villain in my opinion. It's mostly because of his performance that I love this movie so much.

Yes. Totally ineffectual and miscast. Worse than ineffectual - the performance actually plummets into cartoonish Pirate Parody because of the egregiously inept miscasting.

Lloyd was hammy and a bad actor in this movie.
His accent was more like Jim the drunk on Taxi

I always thought when Kruge says "put him on screen", he sounded like Rocky.

Every time I watch this I think Lloyd makes a very poor Klingon. For me it's his voice and the way he carries himself.

There was nothing ineffectual about his performance whatsoever. He absolutely nailed this role & I agree with all those who say his Klingon is the one that all others should be measured by. Also, just becuz his normal voice came through at times, does not mean he didn't act well or wasn't convincing in this part.
The doctors say he has a 50-50 chance of surviving. But there's only a 10% chance of that.

And therein lies the problem: he kills his girlfriend, he kills his gunner, he kills David. But he speaks like Rev. Jim. Maybe he could have tried to alter his voice some?

Exactly what I said a few posts above. The screenplay calls for Lloyd to be a total evil badass with no redeeming qualities, which is proven out by the fact that
He cold-bloodedly kills David, Kirk's son, with no discussion before or remorse after
and a beast who would do that is a beast, who should be shown no sympathy in life and no quarter in death combat. Kirk's last-minute attempt to extend mercy to Lloyd is perhaps the stupidest scene in the ST movie franchise (except for the total mess that was
Final Frontier
).
Lloyd is an evil renegade Klingon who will stop at nothing to acquire the ultimate weapon, yet, we are also to take him as a source of amusement, as with his stupid pet "dog" on the starship bridge, and with his "barbarian bravado" after wrestling the giant worm on the planet surface and even as trailing clouds of nobility as he tells Kirk (not aware of the fact that Kirk has one last lethal card up his sleeve), "I grant two minutes to you and your gallant crew". Now where the hell did that bit of dignity come from? It came from the losers who thought up the line. More criminal inconsistency that drags the film down to cartoon level.
He needs to be either consistenly badass or consistently buffoon. Sadly, the script wavers between the two, to the catastrophic destruction of the character's authenticity, and to the film's detriment. Nimoy hugely misjudged this bit of casting.

I'm not sure what you idiots are thinking, but Lloyd was terrible in this. Totally lame and ineffectual. I like Lloyd as some goofy character, but he was totally miscast.

^THIS^
I completely agree. All I could think of is Jim from Taxi the entire time. That voice came right through that ridged skull and ruined it for me. And yeah, that dog was ridiculous, too.
I want the doctor to take your picture so I can look at you from inside as well.

Cliff: "Yeahone of yer-eh major exports from the nation of Caspiar are-uh those long matches."
Art Vandelay "Yes, but they are among the biggest importers of diapers and latex."
Latka: "That would be due to the rubbar rat population boom. You see, they burrow into the trees, dreenk all the latex, and leave them to dry. The need for excess diapers was because occasionally the rats would mistake a person for a tree. So you see, the rats are both a blessing and a curse."
