I think TPM is less obsurd and more watchable than the other two. The big reason, as already stated, it doesn’t have as much failed attempts to tie things in with the OT, like having Obi Wan learn to talk to Qui Gon’s ghost or Boba Fett being an 8 year old etc. etc. I also think that it’s just easier to sit through; sure it’s convoluted but at least it doesn’t get too deep into the mindboggling confusion as the subsequent two. It also looks the best, and has pretty great visuals (with the exception of some dated CGI), while the others just look completely fake and hideous in my opinion.
