Partly true.
Yes a movie will be faster paced and yes a show has to stretch the action a bit - a weekly show at the pace of the superb 28 Days Later will eventually leave its audience numbed to the action. However, there are definitely lessons that scifi shows can learn from films like this:
1) Tight plotting. Know what the story you are telling is and tell it.
2) All relationships are kept in the context of the plot. This area is where shows like Walking Dead, SGU and Falling Skies have been big offenders. The interpersonal stuff there feels tacked on and in fact at times it seems the plot exists as a backdrop for the relationships. That is soap opera which has no place in Scifi.
3) Little things mean a lot. As Overmind noted, the care and skill shown in 28 Days Later in "little things" (like music properly matching the visuals, using quiet scenes to set mood and even HOW the action is portrayed) make the show. And they do not have to cost lots of money either. Done right they can give a show an "art" feeling - like in 28 Days Later.
I don't disagree really although I would point out that in regards to #2 on your list that with a TV show there will always be
some interpersonal drama due to the fact that we, the viewers, are going to have much more time to get to know the characters. In a way it becomes more personal because we get to know them far better than we do the characters in a 120 minute movie.
Keeping the inter personal drama logical and plot related in a TV show is of course paramount. And it's important not to let the drama become melodrama, like with Lori and the pregnancy on TWD. Sure a pregnant woman in a zombie-filled world is going to have some serious fears and doubts to contend with, but the way they wrung that story line out was just too maudlin and melodramatic. It actually became a turn off, mostly because it was obvious the writers were trying way too hard.
Now I'm not a huge fan of
Terra Nova but I think it is a good example of balancing the the drama with action. There are moments of cutesy cutesy garbage but overall the show keeps the pace tight and moving briskly, even with the inter personal drama elements. If they took that pacing and combined it with the artistry and attention to detail that is in
28 Days Later I think TWD would be much, much better.
