Nah, the consensus (from what I gather through friends, contacts, the internet - both fanboy and otherwise) is that the other two Jones films are viewed as pretty classic in their own right. TEMPLE OF DOOM is the most controversial, but the love for that film has grown over the years, and there's oodles of goodwill and affection for LAST CRUSADE.
And Leonard Maltin's hardly indicative of more than Leonard Maltin and the lackeys he hires to produce his guide.
Yes, but Maltin is famously objective, and very reflective of critical consensus. (Witness the ultra-predictable ***1/2 ratings every year for everything you think will get ***1/2 - if you crack open the new edition of his book each year as I do, you'll find you're nearly always right when it comes to how he'll dish out his ratings. I reckon that this year we'll see ATONEMENT, JUNO, NO COUNTRY FOR OLD MEN, THERE WILL BE BLOOD, etc. with ***1/2, THE BOURNE ULTIMATUM with ***, LIVE FREE OR DIE HARD with **1/2, RAMBO with *1/2, and so on - it's very rare that Maltin will buck the consensus).
I recall TEMPLE OF DOOM getting plenty of negative reviews on release, although admittedly even the hallowed RAIDERS had its fair share of detractors when it first hit cinemas.
But, anyhoo, I'm fairly sure that TEMPLE and CRUSADE are not held in anything like as high a regard by The World At Large as RAIDERS is, and it surely follows from that that if CRYSTAL fails to rival RAIDERS in quality it'll be perceived by many as a disappointment.
Well, I think RAIDERS is the greatest adventure film of all time. The chances of a director equalling that, or besting it, in his lifetime is very, very slim.
I disagree. IMO, CASINO ROYALE and DIE HARD are better "adventure" films than RAIDERS, while T2 is at least as good. Now, by no means is it easy to match RAIDERS, but it's surely doable, especially when you have Spielberg with all the money on earth and many years of development (hell) under his belt.
Neither am I sure that Spielberg is no longer on his "groundbreaking classic" form. Since CRUSADE, he's made some of his best and certainly some of his boldest and most interesting films, with SCHINDLER'S LIST obviously at the top of the list, but there's also JURASSIC PARK, MUNICH, THE TERMINAL, CATCH ME IF YOU CAN, AI and so on. You rightly cite DUEL, JAWS, CLOSE ENCOUNTERS, E.T. and RAIDERS as products of his golden age, but it's hardly as though his abilities have nosedived in recent years.
So I still say that - in theory - CRYSTAL could be as good as RAIDERS. And I also maintain that - given all the time and trouble spent on it, as well as the incredible amount of fan anticipation - it should be as good.
