<human>: So, my girlfriend (of 5 years) keeps asking me to watch a certain anime series with her. She has already seen it, but wanted me to see it too. Although, I'm generally adverse to shows such as the one she has been asking me to watch. 

There's a simple solution, though, right? Just watch it with her to make her happy. So I did, I watched the first episode and some extra material with her. And then she asked me, "So, what did you think?" 

I try to be as honest with people as possible, so I responded, "Well, it really isn't my thing. I probably would have enjoyed it when I was younger, but not really now," and listed some reasons why. There's certain parts of the show that make me uncomfortable, other parts that just seem silly to me, etc.

She still wants me to continue watching it, thinking I will grow to like it. I feel like if I don't watch it, and actively don't grow to like it like she does, she'll be upset. So, what do I do? Do I watch it and feign really enjoying it? Do I continue to watch it and continue to be honest with her?

I'm sure the solution to this is common sense, but I'm having trouble figuring out how to respond.

Give me the gist of the text in a nutshell
