CASPER 2: A SPIRITED BEGINNING(1997):

WOW! This movie is as bad as most of the reviewers on
IMDb say!! Even the great actor Steve Guttenberg can't
save this! This has poor and obvious graphics, a bad
script, and really bad acting! Sad too, as the first movie
was actually pretty good! C-

From Amazon.com:

While not as groundbreaking as the first Casper, A Spirited
Beginning is a well done attempt to "fill in the blanks" of
the original and tell a full story about the past of Casper
and his uncles. More comical and light-hearted than the
original, this movie is perhaps even more impressive as
far as visual effects ar concerned. If you sympathise with
asper et al, you probably won't be disappointed. - Anton Yakovlev
