As OliverA said, it depends on your needs and what you consider 'good' and 'easy'. I started out editing movies with Avid products (before Pinnacle bought it) like Avid Liquid. It is (or was) professional quality. It took just a bit to learn the basics and a long time to really be a productive professional. Same goes with the Adobe Premiere line. I dabbled with it back in the 90's in an effort to round out some of the tools I was using but after leaving the Avid Liquid line, I went full-on with Adobe Premiere Pro. Again, a professional product with a professional price and learning curve. But, wow, what you can do! I only edit movies and short videos as a hobby now but, man, I wish I had the tools (and hardware!) they have access to now.
I had a similar question from a student some months back about a video editor that they could just edit some 480p and 1080p vids that was a bit more able than iMovie or WMM but not getting the complexity of the pro stuff. No need for the cutsey theme packs and pre-made stuff. She also needed an actual editor and not just a tool for conversions, splicing, capture and just linear ops. If that's what you want, you don't have to have a full-blown editor.
So, I did some research on what was available out there and ended up recommending Shotcut. It's free, open-source and is cross platform. It's not something I'd recommend to an aspiring/beginning video editor, as its workflow is quite different, but once you get how they have set up their editing and 'filters' usage, it's a fine beginners editor. Give a few hours to the youtube tutorials and you'll be productive in a day.
