See it in IMAX...

Rating: Null/10 (22 March 2009)

I never heard of the "Watchmen" before seeing the movie trailer. In fact, after seeing it, I thought that this would be like more like the Fantastic 4 (which wasn't one of my favorite movies) than Dark Knight.
However, the critics and user ratings are right - this is an amazing movie - if you see it in IMAX. This is how I saw it. I seem to have had a very different experience than many of my friends who saw it on normal sized screens. The IMAX rendition is so striking (both visually and audibly) that any problems in storytelling are shunted into the background. As such, I strongly recommend making the effort to see it on the huge screen if you have that option.
That said, it was well-acted, visually stunning and the pop-art references are fantastic. It is 2hours and 40 minutes long - and, in huge screen mode, just about every darn minute there was something amazing to look at.
It's basically a mystery story about the death of superhero ... in 1985. Although in this version of 1985, the existence of superheros is a part of life (even though there are only a handful).
Whatever you 'think' a superhero or comic-book movie can be like, this movie will challenge that (like Sin City did). It's not a kid's movie by any means. There is intense and graphic violence, explicit nudity and adult themes throughout. My advice is a big thumbs up if you've got an IMAX theater showing it. Since the critics and user ratings for this movie are both in positive territory, I say that indicates it's good flick no matter the screen size.
