Going to the cinema

Yesterday I went out with my friends. We were very undecided on what to do, at in the end we decided to go to the cinema. One of my friends wanted to see a horror film, or at least a thriller. I was very scared to see watch (usually you use watch when you talk about films or television) a frightening film, but I accepted to make happy my friend happy and not be dreary. Well, We saw "The Gone Girl" and I have to acknowledge (I have to say) that it is a very interesting film! There is only one brutal scene, but I advice to see it :) and I recommend you watch it.

Going (or We go) to the cinema

Yesterday I went out with my friends. We were very undecided on what to do, at the end we decided to go to the cinema (we say, 'go to the movies'). One of my friends wanted to see an a horror film, or at least a thriller. I was very scared to see (not wrong but 'watch a movie' is better in english) a frightening film, but I accepted to make my friend happy my friend and not be dreary. Well, we saw "The gone girl" and I have to acknowledge (again, not incorrect but 'I have to admit that...' is more natural) that it is a very interesting film! There is only one brute brutal scene, but I advice would advise anyone ('to reccommend' is better in this case than advise) to see it :)

Your english is perfectly understandable, I think the idioms and expressions of english will be your next challenge.
