^ Well, you know, even though the broad consensus seems to be against Nemesis, that doesn't mean that dislike for it is universal. There are plenty of people who do like it and Stewart could just be one of them. Everyone has different tastes. Stewart is a fan of 'action hero Picard' from the movies too, even though fans seem to much prefer the more thoughtful Picard of the series.
It's also worth remembering that it's difficult, if not impossible, for someone involved in a film to see it the same way as the outside viewer does. Stewart is a lot more emotionally connected to a film like Nemesis than those of us who have given, at most, a few hours of our lives to watching and critiquing it.
Regarding the original topic of this thread, I agree with the fact that it is probably only wishful thinking that there would ever be another adventure for our TNG crew. Particularly with the box office success of the 2009 Trek film. But I would still love to see it, and I don't buy the argument that the actors are too old. Too old, perhaps, for big hand-to-hand combat action sequences, but those types of sequences are not the heart of Star Trek.
TNG nostalgia does seem to be growing at this point, so chances are perhaps better now than they were a few years ago. But as long as Abrams' version of Trek brings in the money, I doubt Paramount will consider revisiting any past Trek incarnations in anything but DVD releases and syndication packages.
