I’ve said this in many topics but I haven’t watched the PT after 2007. It is possible I once saw TPM on VHS after that for some reason, to check the condition or something. I don’t remember anymore. Anyways, I still remember what happened in them and I can play them in my head if I wanted to (but I don’t), mostly TPM. ROTS I’ve luckily almost forgotton except a few scenes but I would have hard time to explain what happens in what order.
The point is, I love the original trilogy and I remember the time before TPM like it was a full life even though I saw the OT in 1996 for the first time. It was great time all around. After the PT I had lost this feeling. There still were the same movies I loved but with them came this other thing that wasn’t anything like it. So I made the decision, which wasn’t really hard at all, that I wanted that same feeling back where I didn’t know what happened before as that was way interesting that the PT ever delivered. I haven’t looked back since. From a nostalgic point of view it could be interesting to watch them again but I know for a fact that after seeing them the feeling isn’t one bit better than it was before, there no reason for me to disappoint myself as there are much better movies to watch instead.
I feel this is a good take that some of us Star Wars fans have with the Prequels. Why watch the Prequels again when they are not good movies, and take away from the feeling of nostalgia and happiness from other stories we do enjoy in the Star Wars universe?
Or as you say, there are simply many other better films to watch, or re-watch.
