I thought it was quite entertaining. I didn't enjoy it as much as Part 4, but it was still better than most DTV crap coming out these days.
If you liked the previous installments, it's worth at least a rental.

Submerged in a sea of darkness without end.
To feel nothing...hear nothing...for a thousand eternities." - Evoken - Quietus
