I often here this argument for sci-fi/fantasy adaptations. But. No. Most miniseries have shit for budgets. They lack the potential for the proper scope. And sci-fi/fantasy is all about scope. Look at the Dune series for instance. Despite being more faithful to the books, it lacked the mythic grandeur and vision of the movie.
Disagree?
I think when people say X would be better as a miniseries, they often qualify what kind of miniseries. For example, I often read "
Watchmen should have been an HBO miniseries." The implication is that it would have a budget, good directors, writers, be well cast, ect. In general, quality. No one ever says, this should be a sci-fi miniseries, because barring nuBSG, sci-fi ain't that great.
Yeah... "budget" isn't the most important thing, really (though an inadequate budget will always harm a project).
The real question is "what kind of story is it?"
Movies are great for representing "a day in the life" sort of things. Granted, those "days" are sometimes supposed to be hugely transformational days (ie, Luke Skywalker's entire life gets ripped out from under him and a few days later he's a galactic hero... or terrorist, depending on your point-of-view, I s'pose!)
But stories which are supposed to show a lot of characterization... growth and change and so forth... well, in my opinion, those usually fail as movies. Try as you might, there's just not enough time to tell an exciting, entertaining story AND develop a single character, much less and entire CAST of characters, in the time allotted to a movie.
As the days of conventional TV draw to a close, and the days of movie theaters being the primary place to watch films go away... the line between "movie" and "miniseries" will blur, and eventually go away entirely.
I can give anecdotal evidence from my own personal behavior... but I know that a lot of other people do exactly what I do. I've got a nice "home theater" setup... big TV, great sound, comfortable seating... better popcorn and snacks... you name it. And no punk behind me kicking my seat throughout the entire film, no drunk/stoned couple at the end of the aisle giggling and making fun of the film, no screaming kids, no "hey, what's going on" spoken in a very LOUD "whisper" three seats down... and I can pause the flick if nature calls, too!
And I watch almost no "live" TV except for the news, because I hate commercials and "edited versions" and channel ID "watermarks" in the corner and all that nonsense. Plus... again with the "bathroom break" thing.
So I watch VERY few movies at the theater... and I watch very few TV shows in the conventional fashion.
We have DVDs and Pay-per-view and Netflix and real-time-streaming and TiVo and all that... and the old model is fading away as a result.
What does this have to do with the topic at hand? Well, I don't think that "movie" versus "miniseries" is going to remain tied to the existing preconceived "low budget TV versus big budget theater" argument in the future. Regardless of what medium it's initially made for, the real money and the lion's share of the viewing occurs in "on-demand" viewing environments.
This frees up creators to make their works in different ways... with the realization that the amount that they should budget will be based not upon the initial venue (TV or theater) but rather the number of hours produced (and thus the sale, or rental, price of the associated viewing media).
A crappy movie will end up in the $1.00 bin at Walmart today... so the argument about quality, while true, is not specifically tied to one medium/format or another, by the way.
A quality "miniseries" format production could, under this new model, make a lot more money (increased sales price for more hours of entertainment!) with a disproportionately lower production cost (you still need the actor/director/etc time, but sets, props, costuming, etc, can be leveraged over the whole series).
