I am totally amazed at the question.........
"what are you talking about?"
You don't understand the concept that the FX actually stunk in 1989?
'All movies back then are bad compared to modern FX'
No, I too, saw TFF in theaters and the FX were a GIANT step back from TSFS, TWOK & TVH. Let alone the star Wars movies Aliens etc.
Many, many reviews commented on how horrible the FX were compared to contemporary movies (not movies 19 years in the future
Shatner & Bennett hated the FX and said they were not what they expected or were promised by the company.
I'm not saying the quality of the FX can make a good movie worthless or a bad movie great, but by any objective standard they are BAD. VERY BAD.
