If memory serves, Toei wanted to celebrate the 25th anniversary of its SUPER SENTAI franchise. So, they found a way to weave five members of past Sentais plus 24 "Red Rangers" (GaoRed not withstanding) and clips from all 25 (at the time) teams into an adventure with the GaoRanger team.
Toei did a great job with "Hyakuju Sentai Gaorenjaa vs. Super Sentai." Seeing the five main past Sentai members (GingaBlue, GoGoYellow, MegaPink, LiveRed and Big One), plus all 25 "Red Rangers" and seeing various Zords/mecha from past teams attack the main monster gave me chills down my spine.
THIS IS HOW "FOREVER RED" SHOULD HAVE BEEN DONE!
