It is like the Fifth Element, meets 300, meets Battlestar Galactica.... in neon.

Rating: 9/10 (5 December 2017)

What made Thor Ragnarok enjoyable was that it stood well on its own. While it would have been helpful to know and understand the events of the previous Thor, as well as Avengers: Age of Ultron, it was not necessary as enough information was supplied to take what was happening at it's face value.
Honestly though, it was just a fun popcorn flick.
Hulk Smashed, Thor Zapped, and all in all it was just a solid film. No one character outshined the other, and though the dialogue at times was a bit wooden especially with Cate Blanchet's "Hela", it was clear that everyone involved was just having fun with it.
For the Comic Book Fans, the narrative pulled greatly from the Planet Hulk arch, and while it was not a direct retelling, it had enough elements to make it familiar and not feeling contrived. I personally would like to see a proper Planet Hulk / World War Hulk movie, perhaps where Hulk returns to Sakaar in order to lead the revolution that he in part started.
After being disappointed with Thor 1 and 2, Thor Ragnarok could either be a nice way to end the franchise, or an excellent way to jump start it with 3 more proper films that actually get the formula right. This focused more on the mythological elements of the Thor legend, rather than the "Thor in America" direction -- arguably making it a much more enjoyable film rather than it being a fish out of water tale.
To expound on the Summary, this had the fun of The Fifth Element with over the top, yet not outside the realm of reality and reason characters, the epicness and cinematography found in the battle scenes of 300, and a finale that was very reminiscent of Battlestar Galactica.
A solid "A", and a film that I will hopefully re-watch once it becomes available in the usual places.
