The introduction of the Dinozords is a big deal for the Power Rangers movie.
Power Rangers are sworn to only use force proportional to the scope of a threat, which means the episodes would always end with them finally summoning their Zords as a last ditch effort to take down the monstrous invasion.
This is something that kids from the 1990s have been waiting years to see.
Whenever the minions of Rita Repulsa (played in the film by Elizabeth Banks) would take too many hits, the evil sorceress would use her magic to force the monster to grow to the size of a Kaiju.
