Can I ask a question about English? "Do you know anyone who's taken professor Smith's class? " Why "taken" , not "taking"? I thought "taking "is correct because I often use like "l'm taking psychology". Please tell me.

Movies I had some time,so I went see a movie,Fantastic Beasts. It's too late now,right? But I really looked forward to it. That was very good and I was very excited the whole time. The picture was so beautiful. I've seen "Harry Potter" many times,but I got a fresh exciting from that movie because it is different from original "Harry Potter". I've not seen movies for the time being,but I came to realize again how much love I watch movies. That reason is that I could see many cultures and people I've never known. I couldn't know what the world is like. Of course,I like to read books and read it everyday. We could aquire new things and improve our logically thinking. But we actually can't see something. We can imagine many things,though. So I like watching movies,especially American and England ones. They improve my English I think. What a great this is. Please correct my compositions. Thank you in advance.
