Which is to say, for really well *written* comics, the TV series might be a better vehicle than a movie.
Personally, I much prefer the slower story-telling of a TV series to a movie or even movie series. You can layer so much more depth, both in the plot and in the character-building, in a TV series. For one of the best examples, see Babylon 5 - particularly the character arcs of Londo Mollari and G'Kar.
One of the best things to happen in comics was Claremont's run on the Uncanny X-Men, where you had a single writer on the book for over
15 years. This allowed time for characters to grow, some characters to leave, new ones to join, and major changes that felt organic (e.g. Storm being depowered for a few years, and
still kicking all sorts of ass as the team leader). The reason the Phoenix and Dark Phoenix saga was so awesome wasn't that it was cosmic and stuff, it was because it was told over a span of four years, with Jean gradually growing in power due to the Phoenix influence and then becoming corrupted through the machinations of the Hellfire Club.
Now, comics are more movie-like, with the six-issue story arc being the standard as opposed to the episodic/continuous story. You also have the plots being disrupted by This Year's Event: House of M, Civil War, Secret Invasion, and so on, as well as constant relaunches in the belief that people are loath to jump onto a comic at issue #256. That makes it hard to work on a continuing story.
