Re: April 27, 2009: "Confessions of a Lapsed Trekkie (Part 2)"
That looks about right. Regardless of the thumbs, I seem to remember both Siskel and Ebert saying that ST4 was their favorite. I always thought that Siskel had less enthusiasm in general for genre films than Ebert; it seemed to be rare when Siskel really liked one.
But I admit my memories are 25 years old now, and subject to distortion.
