Definitely one of my favourites!
I had seen TMP at the cinema at age 9 with the whole family(ONLY time we went as a family to a ST movie - it STILL blows me away that we did that, but TMP was THAT big of an event, which I don't think kids today realize!)and I got into ST in a big way in ealy '83 after reading Joannie's "Making of The Trek Conventions".
After that, I went to see TWoK at the drive in with a cousin and her family during the May school holidays. Luckily I did because this means I can say I have seen every ST film on the big screen!
TSFS was therefore the first ST film I went to see as a full blown, mad, crazy Trekker. As such it holds a VERY special place in my heart and was, at the time, an intensely emotional experience.
