OK, my friends say don't bother with the IMAX so I went to a regular theater this a.m.. It was very good. I can't tell you much without changing your attitude prior to seeing it. If you're a fan, you have to go. It was only $5 at my matinee so I'd say it was well worth it. It held true to all HP flicks IMHO.
**SPOILISH**
I don't like movies that's main purpose seems to be to set you up for the next one. Although this flick had it's "conclusion" it was anti-climactic. If I never saw any other HP films I'd be annoyed at this one for that reason.
