I never really liked iMovie all that well..it just seemed to me to not be as "intuitive" as I was led to believe. It did OK, mind you, but I, like you, was looking for something different.
I recently downloaded Adobe Premier..I found a GREAT discount on it on Black Friday on the Adobe site itself so I couldn't pass it up.
I have just been 'playing' with it a little the past couple of weeks, and it is a "powerful" program, compared to iMovie. It is also not as intuitive as I'd like... but I guess as more proggies become more powerful, the intuitiveness goes away.
If my memory serves me correctly, I think there is a trial version of it available for download (I can't swear on it tho....and it was on a marathon surfing day when I found it), but just go to the Adobe site (
http://www.adobecom ) and see if Premier is available on trial.
Premier received some pretty strong, positive reviews when compared to iMovie also.
I have been going to some sites on YouTube to pick up some pointers on Premier, and I must say I am pretty impressed with all the video tutorials available on the Adobe website in support of Premier.
You can set up a free account on Adobe, view the videos, and mark them as read and they are kept separate from the other tutorials there for reviewing later if you must.
If you like iMovie, I am pretty sure you will be satisfied with Adobe Premier....I haven't seen many reviews anywhere where folks are going back to iMovie once they experience Premier.
Good luck!!!!
Cheers!
