Not all the blame is on him. Ellis didn't write an issue for almost 3 years when he was extremely sick. The series basically was September 1999 - October 2006 since #26 came out in 2006, but the epilogue issue didn't come out until 2009. In between that time is when Cassaday was doing AXMen.
But here's the thing about Planetary, it was sooo amazing that each issue was so satisfying that those waits weren't as bad as something like Astonishing. You could also reread the past issues and just look at all the allusions Ellis had been throwing in. Issue #7 has been reviewed, dissected, and analyzed so many times that its reached legendary status as a single issue.
