Do enthusiastic teachers make subject's more interesting?

Whether or not an enthusiastic teacher can make a subject more interesting completely depends on the student. Personally I have always enjoyed school but have been most interested in the subjects where the teacher had been humorous and would incorporated some sort of enjoyable twist on the teaching of the subject(s). On the flip side I had also encountered student from those classes that had zero connection to what was going on and would still refuse to do anything in the classroom. Is the a reflection on the teacher? I like to think not.
