While Marvel's R-rated "Deadpool" dominates theaters in wide release this weekend, the specialized side is at best treading water. The usual range of Oscar contenders continue to add to their totals at a pace similar to recent years. The major new release, Michael Moore's "Where to Invade Next," which had Oscar hopes, managed a respectable if not sensational initial 308-theater start, with future prospects to be determined. On the other hand, Denmark's anticipated and high-profile foreign-language Oscar nominee "A War" opened at a level below virtually any similar film in its elevated position.
