Horrendously awful
Staggeringly atrocious...
I forced myself through the whole thing, only as a matter of thoroughness. I laughed twice... more of a chuckle actually.
The always excellent Fritz Weaver was interesting in an unusual role for him. Just about the only decent thing in the movie.
It was sort of interesting to see some of the familiar character actors from that era.
That's all the positives I can come up with.
I can't imagine even in 1969 this was considered funny.
