@mookie Ok, so I just finished re-watching #MissionImpossible 1-7 after seeing MI8 at my local AMC.
If I were just ranking the movies for entertainment value, I'd agree with you the MI5 -- Fallout -- probably is the most exciting with MI4 - Ghost Protocol a close 2nd but, after re-watching all of these films I'd rate them exactly in the order they were released, except for MI2, which I don't think belongs in the series & seems entirely out of place & should be rated last because of that.
If you consider them all together, they really are a serial starting with MI3 each containing links (#EasterEggs) to others in the series & when I looked back I saw MI5 & 6 (Rogue Nation & Fallout) being parts 1 & 2 of the same movie, like MI 7 & 8 (Dead & Final Reckoning) are, & so cannot be rated separately IMO,
So, this is my rankings for the series:
1: MI 1
2) MI 3
3) MI 4 - Ghost Protocol
4) MI 5/6 - Rogue Nation/Fallout
5) MI 7/8 - Dead/Final Reckoning
6) MI 2
