It's all subjective (though we can probably agree on "inferior to the original" statements). Again, from childhood, I saw JAWS 3-D before I saw the original - in the theater on opening weekend during a hot summer. We went directly from the movie theater to our local swimming pool and I refused to get in the pool. I was 6. So JAWS 3-D had the identical effect on six year old me that the original had on everyone else - and I distinctly remember thinking the ending (grenade stuck in the Jaws) was cool, too. Never revisited that one either. I saw JAWS a few years later and of course it's better. I didn't dislike JAWS 2 either though.
Great cast, fun action, though I agree it is a lesser film than the original.
