Saw both King Arthur and Alien Vs Predator in the past couple of days. Both were entertaining. Certainly worth the rental price.
King Arthur is a new take on the Arthurian legend, set many hundreds of years before traditional tellings of the story. All the favourites are there, but it's based in a time of a sagging Roman empire, and Anglo vs Saxon warfare. Interesting, and I thought enjoyable.
Alien Vs Predator gave slightly more than I expected. Of course, I expected very little. However, it was fun, nice to see the "predator" in a different light, and the gooey-evil-razor-teeth-acid action of the "aliens" is always fun. I can say this, it didn't disappoint (well, except the little bit at the very end...)
