Me? I don't care about the implausibility of scientific procedures and alien processes in a sci-fi movie? Really? The last scientifically-plausible science fiction move was 2001 in 1968. The book has been thrown out since then.
The thing that really, really, super bugged me was:
But I actually enjoyed the film up till the last 20 minutes, when it went too far gay.
. Other than that, the film was fun, gorgeous to look at (and 3-D that was pretty and not overdone), had some fun characters, and fun Try-To-Top-Ripley situations for its heroine. As mentioned above, many things were unbelievably dumb - but I've long since abandoned wondering how such things can get past the script and production stages of a zillion-dollar motion picture.
Overall I liked it. But I went into the, um, Alien Prequel expecting a pulp sci-fi horror film. What was everyone else expecting??
