OK, just got back from my girlfriend's an hour ago. It was pretty fun/funny. Typical SpongeBob humor, and not as much adult humor as there was kid humor, but still enjoyable.
Patrick steals the show, of course. I don't know many who don't favor him over all others. He's very "leggy" at parts, and that got tremendous laughter.
David Hasselhoff's role is more than I imagined actually. He's funny too, and seemed to enjoy the whole thing. I found that in and of itself funny.
I like Plankton but he was underused IMO.
The various "citizens" also are always a highlight. Usually great lines.
No real use of Sandy Cheeks, which was a negative in my book. A good 3rd dimension to the Bob/Patrick duo. THey used Squidward more than Sandy. Bummer.
Not much music, but had they incorporated some more things like at the end, they could've definitely had the "older" crowd laughing more.
I liked it. I don't know that I'd recommend any of you rush out to see it or NOT wait for a DVD of it. I did like it though.
Oh, and the E3 teaser trailer was on before. The LFL logo hit and I went ape **** (silently, but still in a giddy kid-like fashion), and my girlfriend just laughed. She asked "Is this the trailer you keep playing at home when we're on the phone", and I just nodded. She watched it then with interest. She seemed to like it. Yay!
Seeing the trailer on a big screen has me so pumped up for Star Wars. I seriously am needing a bigscreen SW fix right now, but my TV's too small to get that feeling.
