Well that depends which translation of the Republic you are reading. Mine translated version was by Allan Bloom and he did a good job by explaining in the footnotes where the dialogues and the Philosophy separate. There is another version by William C Scott which has more Philosophical foot notes. Which is great for Philosopher scholars than for literature readers (like I sometimes tend to be).
The Republic isn't an easy book to read but if you chose a translator that you feel comfortable reading, then I suggest the book. I would never suggest The Republic for any of the book clubs I visit because it is very political. That's why I would suggest a book more like Ovid's Metamorphosis simply because is easier to read plays than theory books 😉
my luck was awful getting this book...went to the library last week to get and they had to order it..havent heard from them yet..so I went to waldens and the only copy they had was this beautiful hard back one that was 30$ eek! I just wanted a little paper back so I could carry it around with me..so any how Ive read a few of the books on line and I think homer is great! I must admit something funny though I keep picturing the characters looking like disneys Hercules ones lol!
