I was finding the anime selection on Netflix and Amazon lacking, so I decided to try the one month free trial to Funimation a large anime distributor, and after a month I can tell you that this is one of the worst streaming services out there.
When I went on the site it did look like they had a lot content with some shows I had never seen before, and your supposed to be able to watch it in its native language with subtitles or dubbed in English even as it comes out in Japan, but the problem is that the site is so slow you can’t really watch any of it. It is all stuttery, and the site is super slow to even search the site for shows to watch in the first place.
I love the idea of a good anime streaming service, but Funimation is not it. I hope they can figure it out, and maybe I will try it out again later after they have worked on their service a bit, but for now no one should use their service.
