I'll watch 'em all again but I never really liked Search for Spock, Insurrection or Nemesis so I'll view those *maybe* once every couple years.
The Star Trek films really aren't all that bad just you have some REALLY good films (TVH, FC, TUC) and some really poorly made flicks (Nemesis, TFF, Insurrection) and since there's so many films total, it's easy to lump them all together as "good" or "bad"
