I think the PT should be watched, atleast once. It gives backstory to our beloved Star Wars Universe.
Is it perfect, no, it’s not, but deserves a chance to be seen by anyone who wishes to watch them.
Should the PT be seen before OT? No, it shouldn’t, since it would ruin a spoil a lot of the key moments in the OT.
I’ll probably be destroyed for what I wrote, but whatever, it’s the Internet.
