Lapyuta (Castle in the Sky), more than any of Hayao Miyazaki's movies, brings the joy of storytelling to the audience. It is the kind of movie that makes one feel like a kid again; it's just magical. It's a crime that it took this long for it to be released in the states, but now that it's here check it out! And stick with the original language; the dub changed my impressions of the characters somewhat, which is something that should be avoided at all costs in a translation of a movie (or book, whatever.)
I give it a ten/ten.

Who was George C. Scott? George C. Scott was a renowned actor. Practically any movie that he's been in is the better off for it. Now ol' George had absolutely NOTHING to do with this movie..., but he once said something that describes said movie to a T.
I don't recall his exact words, but he basically said that Great Writing can Save Bad Acting, But Great Acting CanNOT save Bad Writing. Never has this little observation been truer than in "The All New Adventures of Laurel & Hardy: For Love or Mummy".
The casting of the two leads was absolutely perfect. Bronson Pinchot (Laurel) and Gailard Sartain (Hardy) not only look the parts, but they do an exceptionally good job at mimicking the real deal (mannerisms and all). This movie should stand as a lasting testament to their talents. That said, this movie falls flat on its face when it comes to (you guessed it) WRITING.
Aside from the opening dialogue between Pinchot and Sartain (which was very "in character") and a brief gag involving a taxi, this movie is an absolute chore to sit through.
PROBLEM # 1: Too much time and effort went into the plot.
I don't want to know why the mummy wants to kidnap the pretty British lady. What I WANT is to see Stan and Ollie (or at least, their stand-ins). Way too much screen time was devoted to explaining the plot or to the not-very-funny secondary characters that said plot revolved around.
However, even if this movie had been all jokes, that would still leave us with...
...PROBLEM # 2: Most of the jokes are what I would call "watered-down" slapstick.
What do I mean by "watered down"?
In slapstick, a character gets hurt in an exaggerated way for comedic effect (ala Looney Tunes, 3 Stooges...,or how about Laurel & Hardy?).
In "watered-down" slapstick (as I define it), a character gets mildly hurt or inconvenienced, and the filmmakers play that up for comedic effect.
Maybe an illustration would help:
In Looney Tunes, Daffy Duck gets shot by Elmer Fudd. His bill falls off and he puts it back on. That is classic slapstick.
In this "gem", Ollie accidentally bumps into some people. They turn around, tell him to be careful, and continue on their merry way. That's not slapstick. That's not even funny. That's just...boring...and this movie is full of these kinds of jokes. It's as though they're this movie's bread and butter. The writers and directors just take these dull moments and act like they're supposed to be funny. Granted, the example I just gave is the most extreme case, but I can only cut it so much slack.
Long story short: The film just doesn't work because the script fails to capitalize on Pinchot's and Sartain's abilities to impersonate Stan and Ollie. Instead, the script capitalizes on plot exposition and lame jokes. Watching this movie is basically watching two excellent impersonators who were given no real material to work with.
Not a good movie, but an incredible sleeping aid.
I say give this one a miss and stick with the real deal (just so long as you steer clear of "Atoll K" and "Be Big").
