I was scared by "previews" which said the editing was too chaotic. My experience is mixed. In the first 1/3 of the film, there is a ridiculous number of cuts in the action scenes (didn't like it), but afterwards this wasn't a problem. So yeah, chaotic filming at the start, but much more enjoyable/conventional for the middle and end.
(P.S. There is at least one VERY scary scene in the first 1/3... despite the chaotic cinematography!)
This film TRIED to tie up all the loose end of the franchise, but it didn't do very well. At least we get to see Claire Redfield again... she looks hot as always, but we don't see her much, and she doesn't have anything to say about K-Mart or her brother, Chis Redfield!
The biggest disappointment for me was the lame death of the "big bad" ... that is, Wesker. I won't spoil his demise here, but let's just say it was Dues Ex Machina... (for those without a Latin background, it means an ass-pull by the writers!)
I guess Wesker was too awesome to defeat in a fair fight! Anyway, the final battle of Alice was against SPOILIER Dr. Isaacs! Actually the final battle was against Dr. Isaacs and his clone!!
I have mixed opions about this film... it tried, and in some sense succeeded in giving a finality to the movie franchise. But it also failed in many ways. The 3D was pretty crappy compared to the last two films ( I just learned they filmed this one in 2D and then up-converted it to 3D in post-production... unlike RE 4 and RE 5 which were REALLY filmed in 3D... so yeah, the human eye [at least my eye] can spot the difference between real art and AFTER-THE-FACT-POST-PRODUCTION cinematography).
Also, they completely skipped what happened in Washington DC (the end of the previous film). There is one line in the movie which referenced this... basically "Wesker betrayed Alice and didn't REALLY give her back full power of the T-Virus". As a fan, I found this lame 1-liner very dissatisfying for the series finale! :(
So now you may think I am an RE hater, but that isn't the full truth. I felt this film was literally too dark, and the 3D was merely acceptable (not fantastic like prior films), but it did give a conclusion and explored upon things like clones of Alice...
I guess the only/biggest fault is the plot in the final scene... an air-borne virus, which will literally take years to work (according the movie itself!) manages to kill hundreds of thousands of zombies IN AN INSTANT... at the movie's climax... this is too convenient/stupid to be believed by anyone... even an RE Fan like me. I'm sorry, but can you say EPIC FAIL?
== EPILOGUE == This film tries, and in a few cases succeeds, to tie up the Resident Evil franchise. But the fake-3D FAILS compared to the real-3D of the prior two films. The horror factor REALLY IS much better than the last 3 or 4 films... but is it enough???
