As a long time fan of the Resident Evil/Biohazard series, I can say this movie was average. If you just want to see your favorite characters do cool stuff, ok sure watch it, but if you're looking for an actually good entertaining story, it's a pretty big dodge. If you've never had with the resident evil series, then don't even bother watching, because unlike past resident evil movies, this wasn't very entertaining
Enjoyment: the most important factor
I don't mind a movie with a stupid plot nor other bad characteristics, as long as it's fun and keeps me entertained. Was this movie fun? Hell no. Halfway through the movie, I thinking to myself "Man, when does this end?". Unlike previous Resident Evil movies which had a big Unga Bunga element to them but were still very enjoyable with tons of cool moments, Biohazard Death Island is a chore to watch. It felt like running through the Sahara desert, desperately wishing for water, but you can't even see a god damn mirage of an oasis
Plot:
It's more of the same. Random crazy person with some past trauma tries to use new zombie virus strain to do evil stuff, and our main characters have to stop him. Along the way, a bunch of civilians and side characters always die, but no one really cares because it's not the main characters
Characters:
I mean, it's the protagonists of the Resident Evil games. You get to watch all your favorite characters interact with each other and do cool sh*t... but then there's the random generic villain number 59# and 60# who no ones gives a sh*t about. I legit just finished watching the movie and have already forgotten their names
Voice acting:
I rarely talk about the voice acting, but god damn, it's kinda bad. Some characters' voice acting is noticeably bad to the point where you laugh due to the complete lack of effort. It's as if they just did 1 single take and the director was like "Yeah whatever, let's go with that"
Visuals:
The visuals are overall pretty good. My only criticism is that some characters' movements seemed really stiff, and I feel that the fight choreography is worse than in the past movies
Conclusion 5/10
If 10/10 is the absolute best movie you ever watched, and 1/10 is the worst most garbage movie you've seen and 5/10 mediocre, I'd say this was a solid 5/10, pretty average overall
