Barely a 3/5, for Fairy Tail standards it was decent. Half of the chapter was utter horseshit. The Erza vs images was Zorro vs Monet all over again. It isn´t unique to either manga, Hiro Mashima used this writing conceptions even back in Rave, but this is Horseshit compared to Zorro vs Monet because those enemies used to be threatening at some point in time.
This Manga has two major issues Pacing and incosistency. All the other Bullshit could be forgiven, especially with Hiro´s level of Art. No one cares about fanservice if he gets 5 chapters of proper action. One Piece pulls the same horseshit occasionally but it´s spread out wider and therefore not recognized.
Hiro Mashima take notes, Taizai although the art looks like filth managed to sell several times better and it has the same fucking premise.3 more chapters, extend this fight for 3 more chapters and it would have been good. But no, a single chapter fight over on some intimidation bullshit.
This chapter actually makes sense. Erza leveled up, those guys didn´t. Hiro uses RPG logic here. You don´t have issues with enemies you fought during the early game when you are at the final dungeon. That´s all Neinhart is he´s an RPG Boss. He makes you face bosses you had issues with early game, but now you´re equipped with awesome shit and fireswords and are level 500, those enemies aren´t intimidating anymore, why bring them back in the first place.
