A below average story, plus good VFX that is what 2.0. audience understand that these are not relastic movie so everything is possible. But even in unrealistic movies you need to set a limit on what your super hero or super villain can do or can't do. This makes 2.0 tad boring.
Ex I can give you, our chitti is fighting a bird demon(that's okay) but after long sequence of fight his battery goes low?? Hello TheF you have a superpower, super ai Robot can't you solve battery issue.
At some point movie seems to be horror movie rather then fictional movie as AK ghost comes inside Sir(spoilers alert).
1.9 for 2.0(1.8 for VFX)
