My initial skepticism about casting a Mos Def to play Ford had subsided into "hmm, we'll see, it could be ok". Until I saw this.
Secondly, Zaphod is totally and completely stupid. I actually though that he was going to be the one that was done to perfection, but seriously, its just crap. And since when does he have 2 heads, one underneath the other!?
Add to that the fact that I recognized like 2 scenes from the book (keep in mind that this is referncng the omnibus edition, which plainly states that "whatever is wrong here is wrong for good") and you can see why my Hype-O-Meter just dropped significantly.
