I've been having this same discussion with myself. I've been accepted to Chapman and LMU for an MFA in screenwriting. Actually, I've made my decision to go to LMU (unless UCLA and USC decide they want me). What it came down to for me is that I want to be in Los Angeles. I feel like it will be easier to network in the city. Also, LMU's coursework appealed to me more than Chapman's, and I found that LMU's graduates seem to have better success at working in the industry (based on google and myspace searches). However, if I were a production major, I think I'd lean toward Chapman.
