The eighth season of Charmed aired during the 2005-2006 TV season. The showrunners actually did not think that the show would be picked up for an eighth season, which is why the season seven finale was written as if it was a series finale, with the girls "dying" and taking up new identities in order to live normal lives. The show was brought back for what would be a final season on a shoestring budget which required a lot of changes to be made to the show. The biggest among those changes is that many of the recurring characters that have appeared throughout the series were written out, and Brian Krause was downgraded from a series regular to a recurring character. And, the show did not get as many of the big guest stars as they have had in years past, or as many musical acts. In fact, the only popular musical act this season was an appearance by Liz Phair. The big addition to the cast was the character of Billie, a witch who basically teaches herself magic (and ninja skills), played by Kaley Cuoco, who had just wrapped up the series 8-Simple Rules.
This season had a much better serial arc and mostly dispensed with the monster-of-the-week format. The first third of the series was devoted to undoing the events of the season seven finale and figuring out how to have the girls go back to living their lives and not have to use two sets of actresses, as well as coming up with a way to sideline Leo for much of the rest of the season. The second third of the show sets up what would be the final battle, of course throwing some twists in the plotline, and the final third of the season wrapped up the series.
For those who get the blu-ray, like the prior seasons, this one has German and English language options. This is also the first of the blu-ray sets to have any bonus material, and there is a lot. There are commentary tracks on three episodes, and then over three hours of behind-the-scenes and making-of featurettes that really span the history of the show, not just season 8. Most of them are ported over from the DVD releases and contain interviews with the cast, showrunners, and even fans of the show from around 2006 and 2007. There is one interview with one of the producer/directors of the show from 2021, which was created for the blu-ray release, but that is the only new bonus feature. There are no interviews with the cast members that were created specifically for the blu-ray release.
Overall, the season is good. I think it is better, on the whole, than season seven was, with a better "final battle" storyline, better bad guys, and a bit less campy. Unfortunately, because of the budget cuts, Dorian Gregory did not return (the character of Daryl was done dirty by the show for years, however), and Brian Krause was really only in the show for the first third of the season. And, Shannen Doherty was not brought back or did not come back for the finale. I have seen interviews in which she indicated that a pitch was made to bring her back, but the way in which they would do it made no sense. In the commentary track on the final episode, the showrunners only said that she could not be brought back for a number of reasons. Those reasons may have been money, they may have been because of her feud with Alyssa Milano, or a combination of each. But, the show was able to include some of the former stars here and there throughout the season including Finola Hughes, Scott Jaeck, Wes Ramsey, Drew Fuller, and Jennifer Rhodes. There was also another flashback episode in which we got to see Cole and some of Paige's other boyfriends.
Ultimately, I think the show did a good job wrapping up the series. I do think the budget cuts hurt the show not only because of the characters that we did not get to see but because the special effects were closer to what they were when the show started in 1998 than what the technology would allow to be done in 2005 and 2006 had the show's budget been larger. And, they ditched the opening theme song that played over the opening credits from seasons 1-7, to the instrumental that played during the closing credits. So, while the season was not perfect, I think fans of the series will be satisfied with how it ended.
