There are composers who compose new pieces in the styles of previous eras. Plenty of jazz groups (mine) play in by-gone styles (mainstream ca. 1955). I write new songs in the style of "standards" (like Gershwin, Ellington, etc.).
This production, yes, is like a KISS cover band . . . that writes new songs in the manner of KISS! And if you like classic KISS, that's a good thing.
I'd rather watch something in TOS style that has a new story than something in the JJ style that re-enacts scenes from a famous, much-more-emotionally-involving predecessor.
YMMV. Peace be with you.
