if you want a satisfying good ending then just finish the anime on Season 4 and skip the Season 5, but if you want a good ending with absurd and boring storyline, antagonist with an advanced version of Mimasaka, and cooking with a weapon and clown outfit then just watch Season 5
And also on this season, i feel they better change the title to Shokugeki no Nakiri instead Shokugeki no Souma.
But even though I don't really like this season, the last song in last episode was a good though (Its Season 1 OP but with Piano Ver.) i would like to add those song to my Spotify playlist.
