Sometimes TV series need to know when to quit you instead of dragging it out....

So I'm currently re-watching my seasons of Weeds and it's occurred to me that this show, as much as I love it and others, need to know when it's time for them to end. I know that the studios that produce these shows pretty much control this issue, even though in interviews the creators claim that they ultimately decide when their shows come to an end, but sometimes it doesn't seem like the case. It's hard to pass up a big contract promising more money to keep your show going. And also I'm not going to try to understand how all this shit goes down in Hollywood, I'm just a simple man on his laptop voicing my opinion. From re-watching Weeds and some of the new episodes, I've come to conclusion that this show should end this season even though it hasn't been announced and I think they're planning an 8th. Much as I love watching Nancy Botwin and all the situations she puts her family and friends in leading to disastrous results, the show has in my opinion, reached all the possible storylines they could do with this show. That includes what I've seen of this season so far. Which makes me wonder if creators really do have an ending mind when they create these shows or it's all bullshit when the say so in interviews. A perfect example of this is Lost. The creators always went on record of having an ending and it was going to last five seasons, but they ended up dividing the 5th season to do a 6th season and drag out the story. The last season, as much as I enjoyed it, just seemed to add more mysteries to an already long list of mysteries. The final episode didn't close out a lot of them. I have a love/hate relationship with the final episode. Love how all the characters stories ended, but hated how the mystery of the island was never even answered or any attempt was made to answer it. Which made me conclude that they never had any explanation for it and was banking on people caring more about what happened to the characters than the overall mystery of the island. Which, if true, is pretty fucking stupid. This is what worries me about Weeds and other shows I enjoy that are ending this year.
Take for example Rescue Me. One of, if not my favorite show of all time. Season 6 should of been the final season of that series. Did I enjoy the season? Sure, but I have a feeling that after this final season we'll look back and say, "Maybe they should've combined seasons 6 and 7 to be the final season." I say this because some storylines weren't too terribly interesting or just seemed like it's been done before. The Shield was guilty of this. Season 6 wasn't that bad, but overall it seemed sort of directionless and the finale was flat. Season 7 was much better than 6, but also dragged out storylines more than they should have. I think the show would've benefited from combining the two into one 13 to 15 episode season. I mean, the Shane and family as fugitive arc went on longer than it should have and made you stop caring about what happened to them. Other than that minor quibble, The Shield had a satisfying series finale. The fact that in two episodes they were able to change the tone of the show from you rooting for Vic Mackey to thinking he's an evil son of a bitch who just used people, was pretty incredible.  Also, isn't it an interesting dichotomy in our society that a majority of us hate cops, I mean we respect their profession, but we just dislike them. With that feeling in mind we also love watching shows and movies about them. I find it interesting. I know right? Sorry I was talking to my inner monologue. His name's Montgomery and we have a rollicking good time together (to quote the Joker, "I'm not crazy. I'm..... not.)

So I guess what I'm getting at is we all have a fear that shows we have invested in either wear out their welcome (That 70's show, X-Files) or end up ending in a disappointing or conflicting way (Lost, Seinfeld). As long as Entourage and Rescue Me don't fall into the latter category I'll be happy. Friday Night Lights proved they can end with an amazing finale. As long as they don't sell out like Scrubs did when they came out with that bullshit "Final Season", when they became teachers after the year before's finale should of been the series finale. That was one of the most satisfying finales I've ever seen, but was ruined because they rather drag the show out and end it on low note because ABC thru some cash at them. I mean shit, you're already rich from the successes of the previous seasons! Don't be money grubbing whores. Aw well, Hakuna Matata!
