Definitely a great movie. This movie is not at all anything like those Power Rangers TV series. This is more for adults than kids. It is as Dark as DC movies. It has a comparative level of MARVEL & DC both.
I have seen a lot of superhero movies. And like DC or MARVEL, Movies take a lot of Boring time to build up superheroes. But this movie is totally different.
Every moment in this movie is an Adventure. (Little spoiler ....... ) They even don't become Armoured Power Rangers till the last hour of the movie yet, everything keeps you attached to the story.
Every segment of this film keeps you wondering what will happen next. Every next scene feels like an adventure.
Acting in this movie is way better than those of TV series. It's like that, this movie is based on the Real-world, unlike comics.
You can guess what I am trying to say, by thinking about every movie of Batman which was made before the 'BATMAN BEGINS' TRILOGY, was comically made and then there are those trilogy movies and MAN OF STEEL, the approach is based on the real world ( proof ? The Red Underwear Removal of Superman in MAN OF STEEL ! ).
Every actor from 5 has performed well and deep. The audience can connect to them.
And the Concept, special effects makes it truly worth to watch the movie.
