Five star main event. The people complaining about filler know absolutely nothing about wrestling. The whole purpose to the start of that match is to establish layers. Okada is better than Omega but Omega won't give in is the story at the end but that's just as fitting at the start. All the chain wrestling had Okada coming out on top. Omega loses out almost everywhere. Okada cops an injury after his tope con hilo and Omega, instantly, is on it like the villain he is looking for an edge. Despite that, he still can't put Okada away and Okada like the god he is puts a fukking thrashing on him. They do the towel spot and the match kicks up another level with Omega refusing to die and Okada doing everything to kill him. This was so detailed and special and a truly epic story and match. You can take that filler talk the fukk outta here though.
@Jmare007 already said it but there's a difference between establishing layers and working the leg for 10-15 minutes until both wrestlers conveniently forget about and ignore it for the entirety of the rest of the match. If Omega working Okada's leg ever came back into play in the rest of the match it would've had a place, but as it played out story-wise that leg angle was nothing but padding of the 60 minute length.
And I don't mind the match going 60 minutes at all, because once the match entered the next phase of its storytelling it became truly great, but I can't give them a pass for reducing the leg angle to even less than an afterthought after it was the focus for the first quarter of the match.
To compare, look how Naito vs Tanahashi from beginning to end was about them working each other's injuries the entire match and seeing who could endure it the most. That's how you do an injury angle.
