Origins is slow, and Duel is kind wtf, but homecoming and on are great!
Origins is very dull. But i mean i really dont think you could have given the explanation regarding the fore runners in 30 mins and make it exciting. So yes it was dull but that can be excused for the story background. However, the animation on origins imo is the weakest out of the series and that really hurts it. Honestly it was on the level of dead space downfall bad, but not that great either.
The Duel had interesting animation, but wtf since when do the elites live in pre Meji era Japan. The whole feel to this one felt exteremly odd, and so I dont think it really bad, but especially for someone whose played the games it was just kind of like wtf.
Homecoming is imo when everything turned around, its my favorite, and probably overall the saddest of all the stories. The animation was nice kinda reminded me of pumpkin scissors or scrapped princess. But I think it should a darker or more grim side of the spartan soldiers in a concise and impactful way. Dam, if only master chief made it a little sooner :(
1337 was just hilarious, it was completely left field after homecoming, but it strangely worked well inbetween two of the more sadder tales. I got to admit this one had me laughing the whole time, although i admit i was curious to see Momma.
Prototype was in the same vein as homecoming; and that suit in there has to be the most badass spartan suit every. The guy was practically a mini gundam. But alas like in life lessons we need to learn are learned a little late.
The sniping one was kind of cool as well as we got to see the odst guys in action, a nice nod to the recently released Halo ODST. Honestly, I did not see the end coming, i actually thought the spartan was master chief the whole time, but an interesting twist to say the least.
The last story is the one that was previewed on xbox, honestly when i first saw it i didnt like it because of the cgi look, but seeing it in its entirety changed my opinion, not to mention a saucy little blonde hair lady. Plus its the only story to feature Master chief prominently.
All in all I think its an 8.0, I would give specific episodes like homecoming a 10 but the beginning really drags it down. Additionally, some of the stories I think would benefit from longer lengths. Even origins could have been good had it been say a 2 hour movie told from the perspective of a fore runner, rather then a long narration by cortana. Additionally, I kind of wanted to see more of master chief, maybe the can make another anthology down the road. Lastly, I dont get why the couldnt get the voice actors from the game. But I think overall anime fans and halo fans will appreciate, Id say the style of most of the stories reminded me of Mamoru Oshii.
