Well, hysterically bad! Everyone else's comments already hit the nail on the head, so I don't know what is making me laugh harder- this movie or the comments!
I hope everyone involved in making the movie at least had a good time in Italy and Southern California. Hopefully they were laughing, too. Huston was way too much of a genius not to have seen this as what it is- dreadful. Perhaps he thought it was a farce of some kind? I would love to have been a fly on the wall during the after filming drinks Huston, Winters, and Fonda must have shared.
The effects are bad, the dubbing atrocious, I couldn't tell if the weird sounds were music or sound effects, some scenes were lifted almost exactly from Jaws...
I could go on, but I think you've got the idea. If it is rainy outside, and you're bored and ready for a laugh, go ahead and watch.
But don't say you haven't been warned.
