I saw it last night. Enjoyable and a lot of good jokes and humour like the previous one. Homecoming was probably better though story-wise. Some of the action got a bit over-the-top and meh for me at a point in Far From Home, like quite a lot of super-hero films.
Spoiler:
When JK Simmons came back as J Jonah Jameson came back on screen in mid-credits sequence I didn't make out all the dialogue cause a guy behind me shouted 'YES' so I don't know if they were doing a multiverse link up with the previous Spider-man universe, or it was just the character played by the same actor?
I didn't hear a mention of the multiverse in the main film?
Second post-credit scene was weird for me because I haven't seen Captain Marvel so I didn't know what was going on. An alien speaking in Ben Mendelsohn's Australian accent that had shape-shifted to Nick Fury?
