Saw it last Tuesday and am planning to go again this Tuesday. I saw it in 3D/XD (Cinemark) and am glad I did. I think it really added to the visual spectacle (for me anyway). I've been waiting, literally, decades for a FF movie like this, so my view is probably slanted (along with me being a really S***TTY critic).
I was having so much fun watching it and so I was completely unaware of any problems with the editing until I started reading some posts from people who are able to evaluate a movie with more objectivity than I can. It absolutely would have benefited from a little more filling in at certain points in the movie. In particular the news type coverage of their past exploits and Sue's speech. I thought Vanessa Kirby was terrific and her character was the bedrock of the movie.
This was, by far, superior to anything attempted in the past and I give it an 8+/10.
