It is a Resident Evil movie, you can't walk into this one or any of them expecting an epic plot or screenwriting. If you don't get it's simple plot by now, I'll write it out. Alice hates Umbrella, Umbrella hates Alice; in a world filled with zombies it is a game of survival against both the zombies and Umbrella. These movies do not follow any of the game series storyline, so stop expecting that, not going to happen lol
With that in mind, I went to watch it for the zombies and action sequences. I'd have to say Afterlife was entertaining in that respect (the axeman scene was cool as hell). The 3D was done very well, it wasn't a gimmicky in your face injection, it simply gave the film more depth. That added with the Matrix effects made for some very stylish action scenes.
They brought back Claire and Wesker as well as introduced Chris into the series which was a nice pull from the RE games. Unlike most hardcore RE fans, I actually enjoy watching Alice (Jovovich is hot and kicks serious ***), so I'm a bit biased in that respect.
tl:dr - *** loved this movie.
