I remember that, at least amongst the people who I knew (who were fans all from the curious to the big) were very let down by how bad Trek 5 was.Therin of Andor said:
Who says he was angry?
He was more philosophical, IIRC, trying to come up with other reasons for ST V (other than "bad film, bad director") to keep raking in $$$$ after its opening weekend. After all, people had flocked to the other movies, even the oft-proclaimed long, boring one - TMP - over and over and over again, but many only saw ST V in cinemas once.
I even remember a friend making a crack that TFF looked as if the FX was made by an amateur. Neither of us knew back then how accurate he actually was.
