Well where to start with Canaan then, this anime in my opinion was actually really good. I loved the plot of the anime and thought that it was well planned out, although you have to pay attention to the anime to keep on track. The development of the plot helped with character development as the plot at the beginning is quite empty and it picks up during the course of the series.
Characters were already involved with each other before the beginning of Canaan, however as the anime went on you could understand what terms the characters were on and after awhile this shown how closely planned out each character was. The one thing that lets down the whole character development with the main protagonist (Maria) is the way she was portrayed, a 'damsel in distress' and a 'dumb girl'. This was good as it grew closer with the other main character Canaan however it was the same story of what happens when the 'bad people' are around.
To me Canaan had a good animation for the year it was made, it shown detail and different lights in animation during the anime. The animation was well created and gave the 'realistic' anime look rather than a sketchy look, this is what made me like the anime more. The sound in Canaan was also good, the opening especially was well produced and went with the genre and style of the anime Canaan was.
Putting on my 'Yuri-Goggles' now, Canaan shows Girls love like a normal real-life love, the characters weren't on top of each other like other anime. The Yuri was slim and was discreet, however you could tell there was something there between the main protagonists. If your into Yuri anime then this is one that could be nice to see. (Sorry shouldn't go into too much detail here.)
I personally enjoyed Canaan a lot, I found that the enjoyment was good as it kept you wanting to see what happens next, it kept you engrossed to see what the story is about and what happened in the characters pasts. I loved how Canaan itself was quite a smooth running series that didn't just have random fillers in the storyline and didn't have just random unexplained parts.
If you love fighting anime that is not overpowering in the fighting, If you love a simple plot in a story with really no fillers and an anime that keeps you wanting more. I would recommend Canaan, a good anime about girls with guns and some discreet Yuri bases.
Canaan ~
