Rank MI movies

Mission impossible is (for me) one of the very rare long lasting movie franchises, that didn't (don't) get worse with every sequel.

I rank them like this;

1. MI3 - I know many don't agree, but it's intense, smart and fun from the first scene, untill the end. Only problem is some over the top action sequences (but less than in some other sequels)

2. MI5 - Very good sequel

3. Mission impossible (original) - I like the dark tone, almost noir feal it has. I would put it at number 1, if there wasn't that stupid last train-helicopter badly CGI'ed scene, which ruins otherwise very deep and interesting film.

4. MI4 - Still a very good sequel, but somehow I find it less interesting than 3 or 5.

5. MI2 - To much cartonish action, not smart enough, and badly writen charactesr. It's an ok movie still.

What do you think?
