What I believe about this final battle in SMF, is that it should have been a two-part arc or the final episode should have been a one hour movie like Clash of the Red Rangers.
I tolerated the Dairangers, since Season 2 of MMPR was based on it. But since episode 5, I was like, please, no more Sentai. SMF might've been a average season, but Pre-Zyuranger Sentai had no place in this show. Anyways, the fights were pretty awesome, but still, use of Pre-Zyuranger Sentai shouldn't have appeared in Super Megaforce, at all.
God Bless and May The Power Protect You!
