Alias TV series ends in May 2006

Oh too bad, I just heard, my favorite TV series Alias is ending its fifth season at the end of May 2006. Apparently, Alias cost too much to make, have you seen Alias with all the props, the special effects, the gadgets and the high-tech stuff? So it was canned by ABC. I've been into Alias since I first started watching it like 5 years ago, but I haven't been watching it lately since season 4 last year, so I don't know what's been going on. Partly, I didn't know what time Alias was on for this season.
