2.5 -- I rounded up in the poll.
I only watch TSFS if it's with TWOK and TVH. A good movie to watch but, like BTTF II, it's something I don't see as standing completely on its own.
The two things that bother me are leaving Uhura behind ("This is for boyz only!") and that Saavik has much less character than in TWOK.
I don't hold this as a demerit since it gives Kirk a personal reason to hate the Klingons but I wish they could've kept David around longer.
And, chronology arguments aside, TMP came out at the end of 1979 and TSFS in the middle of 1984... how could the public buy the Enterprise's day being over when, in a lot of their minds, it was only redesigned a few years earlier. The rationale for decommissioning the Enterprise should've been that it was too heavily damaged not that it was old and damaged. A slight difference but with the same effect and the Enterprise still seems older than the Excelsior anyway.
