Me Without You isn't a great movie, although it has its moments. It's mainly noteworthy to me because of the performance by Michelle Williams. Like, I imagine, lots of other people, my entire exposure to Williams comes from Dawson's Creek, which to be honest I only watched a couple of times, so I can't say that Williams made much of an impression on me even there. But she's terrific in Me Without You, and reading reviews of her earlier work, it appears that Williams has been a fine actress for awhile now. As for actually recommending the movie, I'll note it's good enough that you'll probably like it if the plot sounds interesting (two girls growing up as best friends in London in the 70s and 80s), but not quite good enough that you'll like it if the plot sounds boring. Seven on a scale of ten.
