Don't expect many changes at UPN this fall. The network's 2002-03 schedule will feature just three new shows: Two dramas (The Twilight Zone, Haunted) and one comedy (Half and Half). Twilight Zone will follow Enterprise on Wednesdays, Haunted will be paired with Buffy the Vampire Slayer on Tuesdays and Half and Half joins the Monday night comedy block. Judging by previews screened Thursday morning at UPN's upfront, Haunted starring Party of Five's Matthew Fox has the best breakout potential. The other two look really bad.
