iMovie or not to iMovie

Well, it looks simple and stupid at the same time. I am used to PC version of Adobe Premier in earlier life, now tried to do something more with iMovie.
There are some issues I found and some other people have found. My issues:
- Titles... it is not clear for user whether the title duration is per title in title set or in total
- Fast/Slow/Reverse video effect is not working (no picture after apply)?
- Themes are not working - plays well in preview mode but after rendering screen remains black?
- Only time indication on playhead, impossible to figure out what the zoomlevel is. Why not to add timecode to timeline divisions?
- Crashes alot, seems very poor quality code.

All in all it seems that this software is made by stupid people for stupid people or something!

I will go for Final Cut Pro in future mac video projects.
