There is no way it is that bad, e.g. worse than DAD. YOLT is a silly fun film but it is kitsch in a 1960s way - it is basically the Bond film Austin Powers spoofs; it has an excellent theme song and opening credits. There is a lot to enjoy about it really.
No, you're reading my list backwards; DAD is my least favorite, and Moonraker is my "favorite" out of those 5.
