Corny, cheesy, below par special effects, even for the late eighties.
Bloody brilliant though.
It's Star Trek, a bit of fun. I personally enjoyed it having been a trek fan for a long time, tos, TNG, voy, ds9, dis, lower decks, picard and strange new worlds (coming soon) and don't forget enterprise which I also thoroughly enjoyed,
So, I liked this film, even the cringy bits.
If you love trek you need to take the rough with the smooth.
