I think of Trek movies in catagories:

Good films overall:

TWOK, TSFS, TVH, ST09

Films that miss in some areas, but have great Trek moments that make them endearing:

TMP, TFF, TUC, GEN, FC

And just plain bad Trek films:

INS, NEM

If I were to grade them:

TMP - B+
TWOK - A
TSFS - A
TVH - A-
TFF - B
TUC - B+
GEN - B-
FC - B+
INS - C
NEM - F
ST09 - A
