Very good Raw
Ambrose-Rollins was a great match. They have really good chemistry.
Hitman bringing out Sami was incredible. And he delivered a damn good match with Cena.
New Day and Cesaro/Kidd were great in their matches/segments. This could be a classic tag team rivalry.
King Barrett and Sheamus make a great team. And Neville got a few moments to shine.
That crowd wanted Reigns to get RKOd bad, and they got their wish.
Very good is an understatement, that was the best Raw of 2015, and by a wide margin.
I agree with all of your points, and would add:
In the span of like 3 weeks, New Day has gone from boring, too extremely interesting. I missed most of the Rollins/Kane promo, because I was still laughing about them yelling, "We did it Kane, we told you we would" as Kane walked by.
Zayn was awesome, he's gonna be the next Daniel Bryan, just a matter of when. Didn't look out of place with Cena at all, and there was a massive cheer in my household when he kicked out of the AA, probably the biggest reaction anything on Raw has gotten in months. I also greatly enjoy the years long tradition of Heath Slater being knocked out by whomever is around.
I'm as into the Barrett/Neville feud, as I am bored with the Ziggler/Sheamus feud. One seems fresh and one seems tired already.
