I liked the whole Jiraiya, Itachi and Pain arcs (Jiraiya the Gallant, Uchiha Brothers and Inv. of Pain) , but everything after that felt rushed to me. Still decided to stick along though.
Kishi could have done a One-Two year timeskip after the Pain arc and it would not have hurt the story at all. Naruto and Sasuke becoming godlike in a matter of months and hours into the war seems far–fetched. Kishi could have done multiple time skips in the war (ex.Month or Weeks timeskip) in order to keep it fresh, but it felt dragged out (Almost 1/3 of the story was a war and again it was only two days)
