What's interesting to me is you mention moments that are epic. And I agree with you. Though I don't think the epic moment was Yoda lighting up the lightsaber. I found that moment to be a bit hacky. To me the epic moment was the huge Jedi attachment fighting the Droid Army. Up until that point we never saw more than 3 force users in combat together, and here we see over 200 (can't remember if 212 counted Anakin and Obi Wan or not) Jedis in combat together. Coupled with the rescue by the Grand Army, it was a high point cinematically. Yoda's battle with Dooku was a chance for Lucas to flex his CGI muscles. I hated it. I wish instead Yoda spanked Dooku with the force. I've never been a fan of the concept that the best wielder of the force is the best lightsaber duelist. We could have seen Yoda using the force to toy with Dooku up to and including turning his lightsaber off and taking it from him. To me seeing Yoda wield a lightsaber, especially in such a bouncy way, was cheap.
Also keep in mind unless you have an early DVD of TPM you're seeing remastered versions. I forget the numbers but there's at least 2 more versions of the film. Including the big one being the 2011 BluRay which featured a lot of cosmetic changes to all the films. I haven't cracked into the 4K ones yet.
McGregor's Obi Wan and McDiarmid's Palpatine were the best parts of the films by a long shot. Almost every new character was cut too short or bad.
Lucas made 2 critical errors in the prequels that if he didn't make would have made them much better.
1. TPM. Listen, the time jump was gonna be risky, but to do it and only recast one character is jarring. I'd talked about this earlier in the thread. If instead we started with the events of AotC, where the movie deals with Anakin's penchant of embracing the dark side to win battle being on show. The second and third movie are basically Revenge of the Sith. The second movie runs very similar to how RotS runs. And culminates with the scene of Anakin walking into the Jedi Temple with the Clone Troopers. The third movie is about the Jedi Purge and exile. We didn't get to see Anakin embracing the darkside much. Here we see him running through the temple with the Clones killing all the Jedi, not just a scene igniting a lightsaber on some younglings. Here we witness Vader embracing the darkside and beating force wielders. Not his destruction of the CIS leadership. Everything else largely goes the same. Again there's small things I would change, but if you instead killed TPM, had Anakin and Padme be known lovers already. Removes the awkward courtship and instead you're focusing on the Taboo nature of their relationship.
2. No new force powers. We saw better versions of force powers seen in the OT, but no new forcepowers annoys me. I needed something. Something to show that Yoda was special, that Palpatine was special. Instead we just got the same rehash of their old abilities.
