I looked at it quite differently. Weve all seen the end of the world/universe/etc. - lets have fun with it this time. After the dour Man of Steel's endless collapsing buildings and superhumans exchanging punches but never hurting each other, I found the light hearted approach refreshing. A confused Mjolnir struggling to reach Thor as he and Malekith battled through the portals was awesome. The fact that Thor so confidently averts universal disaster without a real plan was very signature. I also find it interesting that critics who otherwise disliked the movie felt the fun roller coaster ending saved the film. There's some jarring tonal shifts in the end but Thor was always a wacky dichotomy to me anyway so I totally dug it. But to each his own.
