It wasn't bad. Not something I'll call my favorite all time movie, but it was quite a bit better than I expected. Especially because way too many movies even related to Sci-Fi tend to be poorly done.
Also, I would definitely not call it a Total Recall remake (Which reminds me, I heard there's going to be a Total Recall 2, directed by Jonathan Frakes (Of Star Trek: The Next Generation fame)). The plots between the two movies really aren't close to being the same. Whoever started that rumor, they're way off.
Overall, I'd give it a solid "Worth seeing" rating. If you're a big fan of Arnold, then go see it in the theater. If you like decent action flicks, go see it in the theater. If you don't have a big thing for Arnold, or aren't into action flicks, you might be better off renting it. I don't think this will be a huge blow everything else away 'blockbuster', but I'd be surprised if it didn't do fairly well. It is a good movie.
I also saw a preview for the new Dungeons & Dragons movie, and the new Final Fantasy movie. Both looked pretty good, really.
The D&D movie had some great special effects, which I expected, so it all depends on the acting and plot, now. I've heard good things about the actors, and I know Jeremy Irons is decent, and Marlon Wayans is in it too, along with the guy who played Jimmy on Lois and Clark (can't remember his name;-), so the plot is my big concern. Hopefully it won't suck.
I do sympathize a little with them, though. This has to be a tough movie to make, much like X-Men. if you make it too simplistic, mainstream, and commercial, your real fans will turn on you, and hate you. Same thing if you try to change too much. On the other hand, if you don't introduce it in a way that people who aren't familiar with it can understand, then you end up with a lot of unhappy customers. Not fun.
The Final Fantasy movie looks visually amazing. When it first came on, I think I was the only one in the theater who recognized that it was prolly Final Fantasy. I immediately saw that it was Computer Generated animation (CGI), but I have to admit, after watching it for a minute I was almost second guessing myself. It looked *that* good. I'm impressed. Even if the movie totally blows, I'll watch it just for the visual effects and eye candy. ;-)
