NO SE DICE: I LIKE IT "TOO" MUCH
I am not really sure where this mistake comes from, but it is the basic translation of: "Me gusta mucho". "I like it too much" is not correct because when you use the word "too" it means "demasiado" and therefore, in English at least, is something negative.
We use the word "too" (in this case) when we describe something that we know is not good: "I drink too much beer" etc. The correct version is: "I like it a lot". For example: "Did you like the film?" "Yes, I liked it a lot, it was amazing!"
Hope that helps!
