Well, I'll go ahead and request The Evil Dead, then.

Do the Psycho flicks

Okay after we wrap up Alien, we'll go Evil Dead, the Psycho.

Can we have Romero's dead series after Psycho.....?

I'm not sure whether it can be treated as a franchise or not but how about Argento's Three Mother Trilogy?

I think the way you were going (the alphabetical order) was fair enough.
Btw, you can add The Hitcher in the list also.

Thanks Roshiq. I'll add The Hitcher. If you want the Argento trilogy, I'm gonna need a list of films that it includes since I am not familiar with it.

yeah..It'll be nice to see how everyone grades the films:)
Here are the three mothers:
Suspiria
Inferno
Mother of Tears: The third mother

Great movies, Highly recommended.

I've seen Suspiria but wasn't aware that it was part of a franchise. Thanks for the list.

Alien franchise is done. Here are the grades.

Alien = A
Aliens = A
Alien 3 = C+
Alien: Resurrection = C
Alien vs. Predator = D+
Alien vs Predator: Requiem = D

Franchise Grade = C+

Moving on to fortunato's request....

Evil Dead franchise is up next...

Evil Dead
Evil Dead 2
Army of Darkness

I'll leave this one open for grading until mid day Thursday.
