Like the title says....iMovie 8 lost the themes,,,,which I thought was the killer item of iMovie now its watered down thing like that Windows Video editor..Hell I think even Windown V Editor has Themes....
The themes they had were not cheesy at all, the transitions now and always were cheesy, they just look like Power Point transitions and then throught titles at that, we have a glorified MS Powerpoint movie!!What exactly are you trying to accomplish with a "theme" in iMovie? AFAIK, all a "theme" did was select a matching title and transition. I'm pretty sure you can do that by hand.
Besides... you could do without the cheese anyway. Just do straight cuts and simple titles. You'll thank me (and Apple) in 5 years when you look back at the videos. Trust me.
P.S. to Lars... in all fairness, the other threads don't talk specifically about iMovies Themes.
