I just installed it to see this for myself, and indeed, it is a very crippled version of Windows Movie Maker (WMM). Since WL MM is intended only for Vista users, which already have WMM, I fail to see why anyone would want to use this version. Although you can crop videos, there are no Titles, no timeline, 4 (four!) transitions, limited effects, only two presets for save quality, and probably more things missing. I don't see the Ribbon as having any added value, and so, I have no plans of installing it on my main computer.
