One shouldn't walk in to this movie expecting the best movie ever made, because movies like this are aimed at a very specific audience, and will probably never win any Academy Awards. However, I did enjoy it: it was a light-hearted, quick-moving, fun remake.
If you have deep attachments to the original 80's film, then you probably won't like this version: obviously the plot is a little different, all but a few songs are different, but it is entertaining. Naturi Naughton's version of "Out Here on My Own" gave me chills in a good way.
I think the changes the writers and director made to the movie are appropriate for the audience and generation they are trying to reach. As stated earlier, it's a fun, light-hearted flick.
