A lot of good things have already been said about this film, so I can only join in. The best crossover rider and sentai, one of the best crossover rider and definitely deserves a place in my top movies. I love watching it too.
I also want to note that the creators of SHS found themselves in a difficult position. On the one hand, the 50th anniversary of the franchise required a big story, and the very nature of Saber and Zenkaiger implied a meta-commentary. On the other hand, Generations Forever and Over Quartzer were already a love letter from the riders to their viewers, and by adding Sentai they risked breaking the 4th wall Taisen, which they clearly didn't want. Therefore, it was decided to turn to Shotaro Ishinomori and create a film for him and about him. Hence the details like the mention of characters that look angry or Shotaro from the movie being embarrassed in front of Mei because she fits his favorite type of heroine.
I also want to mention Asmodeus. In such a big crossover, the villain is doomed to remain in the shadows, but his plan was not bad, and the moment when he points Shotaro to the fighting heroes and asks if he likes what he sees is very good. Indeed, what better way to make a person give up on superheroes than to throw him into their world? Especially during another global fan-service brawl.
In addition, I note that in this film, Saber becomes the most important hero in the franchise, because it is he who inspires Shotaro to return to creativity, which means that without his intervention there would be no riders, no sentai, not even Zubat. Amazing if you think about it!
So I will repeat once again that I love this film and finally I will drop my favorite shot from there. Even though it has nothing to do with Saber or even riders, it doesn't change how good this moment is:

Fanfiction is also very good, to match this wonderful movie.
