From a reader:

Every episode of Next Generation ought to have started
with a notification:
This week the Prime Directive is: ON
– every character would rather die than violate it.
This week the Prime Directive is: OFF
– it’s a concept from some other show.
This applied to more than TNG, but it was the worst
offender. Patrick Stewart was great, but there are
more utterly unwatchable TNG episodes than there are
in all the rest, (even if you exclude season one).
