ABC has decided to pull the plug on Alias after five seasons, despite having Jennifer Garner signed through the 2007-2008 season. In one of the toughest timeslots of the week, it was getting clobbered by just about everything other than Joey. Rather than switch it somewhere else, they’ve chosen to cancel it now so J.J. Abrams and company can wrap everything up.I’ll admit the family is somewhat behind on the series this season, more due to our schedules than a marked drop in quality. As a result, I can’t comment on whether or not the new cast members and Garner’s own pregnancy forced such story contortions that audiences drifted away. I will say that its breathless pacing and appealing characters will be missed after the final ep runs in May.For those keep tabs, the show goes on hiatus over the winter, giving Garner time to spend with her newborn. It’ll be back in, I believe, March taking its timeslot back from Dancing with the Stars and then running straight through to the final mission. Please, may it be something other than a Rambaldi device.I also note the cancellation this week of Brannon Braga’s first non-Trek effort, Threshold. My general dislike for Brannon’s work coupled with uniformly negative reviews has kept me from watching this despite an appealing cast headed by Carla Gugino and Brent Spiner. The ratings on Fridays were suffering so CBS sampled it on Tuesday night and it did even worse. They tried to build support these last few weeks by streaming previous episodes on the website since its serialized nature made it tough to sample mid-run.Finally, I want to note the passing of Pat Morita at age 73. Best known to one and all for his work in the four Karate Kid movies, I’ve enjoyed his work over the last three decades or so and will miss his gentle, reassuring presence.
