Look all these wonderful changes and enhancements. The boring walls the empty limited spaces and the close shots were opened up where new shots added to brake the limitations back then.
If we go with the reshooting entire shots then some very boring shots can be replaced for sure!
Its amazing actually with some good rotoscoping can you achieve!
