The thing is eps4-6 had action all the way thro , sporadically. Ep3 was much like this and this is why its a good movie.

Eps 1 and 2 were like 1h10m of ,to be frank, boring crap then some action.

The best scene out of all 6 movies was without doubt the Battle of Hoth. The only really great scene from the prequels , imo was the battle between Yoda and Sidious. That was done superbly , from the cowboy-esque taunts to the flying Senate Pods. I also liked the pod racing in ep1 ..but it kinda felt out of place.

The originals just flowed. The prequels seemed a bunch of set pieces randomly stuck together and "look at these GFX..theyre great ant they?" type stuff.

As for the space action. The originals win there aswell. The beginning of Ep3 was good, it looked great but I wouldnt really call it an action sequence ..apart from the tiny bit with the Buzz Droids..Anakin and Obi Wan seemed like they were cruising lol .
In ep4 you were in the cockpit with Luke etc and in ep6 with Lando. I mean, come on, the Millenium Falcon flying into the Deathstar ,whilst being chased by TIE fighters vs some cartoonish type Buzz Droids ?  no contest.

Id say , dont confuse nice GFX for action.

Everything about the originals is better ..down to such things as ship design. Ewoks also pwn Gungans

Have to agree with all of the above.

Though I do think there are a few more cool sequences in the prequels than Bandu gives them credit for. C'mon are you telling me the battle for Geonosis didn't blow you away? And you've gotta admit the lightsaber action in the prequels is technically far superior to that of the original trilogy, though they make up for that with the emotion behind the duels in the original.

I think in general the technical limitations that they had to deal with in the original trilogy forced them to be more creative to pull off the effects that they wanted within the budget, this resulted in much tighter and better concieved sequences in my opinion. The Star Destroyer thundering over you head at the opening of ANH, the Death Star space battles, Hoth, the asteroid chase. All these sequences more than hold their own today, and a lot of this has to do with a stronger narrative flow.

A problem with a lot of the prequel battle scenes was that you just sort of wander through the action and stuff just happens to be going on around you. With the originals you tended to be more focused on a ship or group of ships as they make their way through the battle, you see things more from the pilot's point of view and these tend to be more engaging, you're right in the thick of it beside Luke as he's about to shove a couple of torpedoes down the Empire's exhaust port. You're suffering from motion sickness along with Lando as he spins and barrel rolls the Falcon through the battle above Endor. You're more emotionally invested in it all.
