“The Bad Guardian” (** out of four) was an earnest but empty melodrama about a woman (Melissa Joan Hart) who tries to save her ailing father (Eric Pierpoint) from the clutches of a villainous and vindictive court-appointed guardian (La La Anthony) who wants to exploit him and steal all his money. Well-intentioned story attempts to shed light on the exploitative and the evil side of elderly health care but it covers all-too-familiar ground and is pat and predictable. 2020’s “I Care A Lot” covered similar material with much more pizazz and sharp satire.
