Bohmian mechanics is a reformulation of Qm which succeds in Solving some issues like indeterminacy, according to its aclaim.
However it has question able postulates:
There are 2 states in defining a system (not in its evolution or pre collapse) , Q(t) as well as Ψ.
This is confusing and physically weak.
Other theoretical and fundamental weaknesses are not accesibily defined in literature, to my knowledge.
