Sno, I hope this ain't a test to measure my dumbness or stupidity, but I'll try to answer anyway.
I got a strange feeling here that there is an ulterior motive in your question though ... but that's fine by me so here goes .....
I really can't answer you directly!
I can only 'rate" how I felt immediately after seeing each of those fine films .... and it's funny that you mentioned Memento.
I saw both those films many years ago and liked each of them for different reasons. But too many years have passed to rate my feelings toward each of them on a scale of 1 - 10.
But I'll tell you what I did like and did dislike most of all about each of them.
Matrix - I liked the special FX - mainly the bullets scene. I disliked the ending which I sort of recall was a telephone conversation scene. Overall - I did not like it as much as the general movie going public liked it. But I considered it to be a likeable SciFi fantasy movie.
Memento - I actually saw Memento a bit before it was released and I do recall it being very unique due to its "time sequences/editing process". This was a movie that actually made you think of logical ocurrences .... not illogical nonsense.
I don't know which version you saw though but the original was excellent
A short while back I purchased Memento for $5 at a video store and watched it only to discover that it had been re-edited .... and by doing so .... all the original 'magic' of that 1st edition was gone.
I gotta admit that I liked both Matrix and Memento, but for very different reasons.
Right now I really HATE the following bullshit which is filmed in way too many movies now-a-days .....
I don't know how many of you GetBiggers have ever blown up a bridge. or a building, or a gathering of 'bad guys'; but I've done one of the above more than once and it is impossible not too watch how much damage and destruction you have caused when the big bang occurs.
But you set the fuse properly and always watch from a very safe distance while keeping your head and ass as low as possible.
But in many of today's movies, the good gang of tough guys always set the charge and casually walk away without looking at or paying one bit of attention to the destructive explosion occurring to their immediate rear.
For one tine in one movie, I'd like to just see one of those guys turn around and look while all the others give him a ration of shit for doing so.
Even better would be to shoot that 'casual walking away from the huge explosion' scene with each of them getting blown away towards the camera in the process.
Don't kill them in the script, but make it evident that tough guys like to watch what they blow up and they know that bad things can happen while trying to look like rough and tough casually walking assholes.
Also I hate those scenes where thousands of bullets fly in your direction and no one gets hit, or panics, or shits his pants.
And don't even ask me about car chase scenes! Or killing kids on the silver screen like that Mel Gibson movie many years ago (The Patriot??). I actually got sick to my stomach in that one.
But the one scene I'll always remember was a scene in an old Paul Newman movie about lumberjacks where his brother (or best friend) gets stuck beneath a fallen tree in a river. At first they laugh at this situation, but they get serious when they realize that the river is rising and it'll take a while to pull him free. And needless to say, the brother drowns while the other bro is doing all he can to save him.
That scene haunted me for years. And still does. (I think it was The Big Trees, but I'd rather not know.
Sorry for not giving a direct answer to your question, Sno .... but I tried my best in a round about way.
Did I pass, or what?
