No, the Big Mom Pirates were a threat on the rooftop at the Tea Party, then the chase happened and other than Katakuri and Perospero, they degenerated into a collection of clowns that failed miserably against a pitiful force of
-half the Strawhats.
-Capone’s crew
-Germa
-two Minks
Which is a force that would be utterly annihilated by
-the full Strawhats
-Kid’s crew
-Law’s crew
-the Scabbards, the samurai and the Minks.
-Big Mom turned into a horror show (not in a good way) and genuinely would have died if not for Sanji
-Smoothie did nothing. Legit, nothing. Other than almost sinking her own ship.
-Daifuku had the piss ripped out of him by Carrot
-Oven was a walking punching bag that, in order, was beaten up by Sanji, Capone, Ichiji and then was fighting Aladine, who has never really been implied to be all that strong.
These guys did not feel like threats, because there was a continal succession of cliffhangers where the Strawhats just kept winning anyway. Despite being horribly outnumbered.
The Raid shits all over the end of WCI. It might just be a fairly regular “Strawhats beat bad guys” arc, but it is far, far superior to the horror show that was the end of WCI. Give me Jinbei, Franky and Robin fights any day over the nonsense we had there.
