I think it's worth it if you stick to it and you are really dedicated to make it work.
I had a blog a while back and it failed, lol. I did perhaps 5 posts in one year. I have recently started a new blog and I have been doing mostly reviews but I remain fairly active on it, adding sexy details of my love life, issues I am trying to deal with and just thoughts I want to share.
It took time for me to get my blog to appear and be the way I wanted it to be, It was a lot of trial and error. But now, I am very pleased with it. It is simple, not overly bombarded with crazy designs, tasteful and even artistic. It might take a lot of time to get started and it will likely change over the course of your work on your blog but it is worth it if you are really motivated!
