I like Resurrection better because you finally got to see what the scientists would do with the alien once they got their hands on them...
being a fan of the comics, i had been waiting for a movie to do that... plus Paul wincott's character is the best and i wished he hadn't died so early, i would have loved seeing him make it to the end and carry on the series with him as the main protagonist...
also, fans of Firefly/Serenity should see similarities between the crew of the Betty and the crew of Serenity(both born of Joss Whedon)...
