It'll open huge, and a huge opening fed by pre-release excitement can carry a film a long way. However, there are three movies that need to be successful, not one. If the huge audiences that walk into the first one walk out thinking 'meh' due to there not being enough compelling story to drive three full movies, combined with the possibility that the visuals turn out disappointing due to
the new frame rate it's shot in, you'll have trouble carrying momentum into the 2nd and 3rd installments.
