Let me say this to start, this is a good nostalgic movie
We get to see how everyone's doing. Everyone looks bascially the same as 10 years ago... except Isshu. I totally do not recognize Isshu until they said his name, he looks older than his elder brother now!
The direct flashback scenes from the TV series brings back the memories of the past, the feelings of watching this series all those years ago. It certainly doesn't feels like 10 years has past already.
While writing the wiki I realized, they didn't tell us what Isshu's been doing, except he's now a womanizer. When did he became a womanizer?! It was hinted that he's with Nanami at the end of the series, what happened to that? Even at the movie ending when everyone's saying what they are planning to do, Isshu just says he's going to do what his brother is doing, which is to join JUNRetsu.
The movie story is simple and straightforward, since all those flashbacks take up time so they don't have time to develop a complicated story.
The kid can fight! I don't mind seeing more of him in the future.
One thing I do not understand is that... If Yousuke knows the Scared Presence is within Tenkai, and the enemy wants to awaken the Scared Presence, what makes him thinks that the enemy would let Tenkai go after getting all the Shinobi Medals?!
My biggest disappointment with this movie is: No Shurikenger
No, I don't mean the new kid. I mean the original Shurikenger that is voiced by Matsuno Taiki-san, who never showed his true face and spoke in broken English. It's fine and all that Toei wants to revamp the character and give him a real face, but at least have the original cameo somewhere? Shirikenger was my favourite character in the tv series so to see him get ignored like that is just sad

My second disappointment with this movie is: no mecha fights.
What's sentai without their mecha fights? I want to see GouraiSenpuujin again...

But overall, I enjoyed this movie and it's a nice way to revisit this 10 years old series.
