You're kind of arguing two different things though.You know, it's kind of sad that people now automatically assume secrecy = suckitude. Personally, I LOVE that Spielberg has managed to keep the film almost completely under wraps until now. Remember how awesome it was to see Jurassic Park "fresh" 15 years ago, and seeing those trend-setting CGI dinos for the first time on the big screen without getting spoiled for all the "good bits" in countless trailers, TV spots, and general internet chatter? I actually kind of miss the "good old days" when the ONLY way to get pre-release information about a genre film was to buy one of those glossy tie-in magazines or read articles in Starlog or simply hope to catch a lone trailer or TV spot (back in the days when there weren't 7 trailers and 50 different TV spots starting a good eight months before a movie's release). What plot surprises are left for The Dark Knight at this point? I'm sure I'll like the film (caveats about the running time aside), but how cool would it have been to have NO idea what Heath Ledger's Joker makeup looked like until opening day? Instead, we got the "Full Monty" back in December, when the trailer was released with I Am Legend. Same thing with Peter Jackson's King Kong. Pretty much every action sequence was heavilly plundered for the advertising campaign. I'm more than willing to give Spielberg/Ford/Lucas the benefit of the doubt on this. If we'd gotten trailers for the film beginning late last year, people would be complaining that they've already seen the movie!
I agree with you about the "secrecy" in terms of plot and I agree how awesome it was when JURASSIC PARK came out and we all sat, stunned and spellbound, by seeing those dinosaurs for the first time. In general, I think we find out too much about ALL of these movies ahead of time now -- there are so many media outlets and such that, you're right, the cat is out of the bag to the degree where nobody is surprised anymore by anything.
That being said, in the "good o'l days" JURASSIC PARK was still reviewed for the press well in advance. No, we didn't know how amazing the dinosaurs looked because the advertising was smart and elusive, but we DID know that critics were blown away by them because the movie was screened in advance of its release date and had a hugely positive vibe the day it came out.
Same on every STAR WARS movie from Parts 1 through 6, and all the prior INDIANA JONES films too. So the question is why is this different -- and why, unlike every other film Lucas/Spielberg have cranked out, were they deliberately trying to downplay expectations here? You can't blame people for asking the question though, because it is valid.
I'm sure the movie ISN'T going to be awful. I bet especially with lowered expectations it'll be pretty entertaining. But this is a classic film series and really anything that's not spectacular is going to be something of a disappointment for a lot of people...just the nature of the beast.
As far as the Tomato meter goes, I'm more interested in seeing some of my respected peers' reaction to it than the "number" it gets from the entire mass of online critics (and sure I'm one of them, but I don't think of Joblow.com the same way I do the Wall Street Journal!) -- but at the end of the day I'm still going in with an open mind. All the lowered expectations among the fans may actually help.
