You know what... I really liked this episode
Natsu vs Zeref got extended a little, just a tiny bit, they added a few more moves and made the final punch last longer, which was not the best, but it was better than nothing, but what really got to me was the music and voice acting, while yes, the fight wasn't long and everyone knows Ichiya's and Anna's sacrifice will mean nothing, but I really felt the emotion and feeling behind the series, and that reminded me why I love Fairy Tail, it makes you feel warm on the inside, Natsu's delivery on that last line and how the animation portrayed that "Bye Big Brother", it had just the tiniest hint of happiness, which nearly made me cry, it showed you that at the end, Natsu probably did care about Zeref, and might remember when he was very young and spent time with him, which makes it all the more heartbreaking, when you know there will never be a time to reconcile with him ever again, which the manga didn't really portray, so that was good, and Ichiya and Anna's scenes were just fun and cool
Overall I liked the episode and do think it did it better than the manga, I won't remember this anime adaptation as the best, but in those small moments, it really can touch my heart, I'm sure the anime only's and those who remember the manga will once again revel in the rant and hatred of Natsu suddenly overpowering Zeref, but for me and those who understand and feel the emotion of Fairy Tail, can just enjoy the little things
Looking forward to the Final Battle with Acnologia, even if it is brief
