I usually watch anime alone. Mainly because I don't have a lot of friends that watch anime. I think it would be fun to watch with other people though. I used to watch anime with my boyfriend until we broke up, it was a fun thing to do together.

Like any movie, I tend to enjoy watching them in a group. I rarely get the chance, but I truly enjoy it more than I do watching it alone.

I prefer watching it alone than with other people. I would feel awkward watching an anime that I really really like when my friends are with me because I would feel like they will make fun of me. Overall,I don't like having other people watch it with me unless I was showing them an anime. (Like,I was showing two friends of mine Shaman King and Fairy Tail.)

I feel awkward watching anything with people.

Both. I enjoy watching some anime series alone, particularly ones I feel my friends won't be interested in... however, I do enjoy watching anime with friends, too.

I do prefer watching it alone, but it's always fun to have someone to watch it with.

I normally watch it alone, but I enjoy it more when I am watching it with others.

I'd prefer watching anime with my friends, but since they aren't into anime, I watch it alone.

You mean other people agree with me!?

When the people I'm watching anime with are into anime as much as me, it's great to discuss the events of the anime with them after each episode. Sometimes we make jokes while watching it, which can make the experience more enjoyable, memorable and funny. When I'm showing an anime to someone who's never watched one before, I feel like I'm introducing them to a whole new world, which is also great. :)

I usually watch it alone, but its a lot more fun to watch it with other people.

Nowadays I watch a lot of it with my partner, it can be fun discussing and exchanging opinions.
I like watching it alone as well, though.
