I wasn't too fond of the writing in DR. It's fun and enjoyable, but it didn't hit the same notes that P4/P3 did. Honestly though, I think a huge portion of that is localization. There's something a little more down to earth in the Persona games.
Also, I find a lot of irony in saying Persona's themes were cute in comparison to Danganronpa's hilariously bad hope/despair nonsense. Persona ain't all that subtle, nor is the plot shakespeare by any means, but I feel like there's just enough subtext beyond the surface theme. The Power of Bonds stuff was really overplayed post-P4 in all the spinoffs, presumably because it was different writers who didn't want to add on to a formula they thought was solid, and ran with what they knew.
I don't want to shit on DR because I did enjoy it a lot, but I just always found to be kind of like Persona Lite in terms of its themes and writing. It's got some damn good character moments though, which is surprising considering how zany the cast is.
Anywho, I hope the localization staff at Atlus USA is up to task for P5. I have really high expectations.
