Favorite Team-Up so far is Ninnin vs. Toq, but Gosei vs. Shinken also has a very special place in my heart.
For summer movie, I'd go with Gaburincho of Music, but I generally enjoyed all summer movies since Kyoryuger. Gekiranger was also kinda fun and, while I don't quite remember the movie itself, I remember liking Gaoranger as well.

I don't care too much for movie power-ups, but Spino Dai-Oh was pretty neat, especially with how they introduced them. Also Ninnin Girls from the Ninninger V-Cinema xDDD

I don't really have anything that I consider "the worst" since I tend to forget about the films I liked less, but I do think that Shinkenger's summer movie was kinda weak and the Goseiger V-Cinema was so-so.
