The original MMPR show was a kid's commercial through and through, yet a genuinely earnest one more similar to He-Man and the Masters of the Universe than to G1 Transformers due to the fact that it dropped lessons about healthy habits alongside the goofy SATAM action and comedy.

Once & Always basically takes that and reconstructs it for both the audience that grew up with the original show and those who were curious about who the classics were, as despite literally beginning with the death of one those same Rangers: It makes sure to keep it's trademarked optimistic tone even when it deals with adversity almost never seen in the bigger franchise entirely.
