I see it differently. I think she's a good candidate overall who made a horrible political decision by releasing the DNA test.
What do you mean when you say her plans have no depth? I haven't read any of the 30+ plans she has released, but I've started looking into her M4A funding proposal and it's certainly more detailed than anything other candidates usually release at this stage in a cycle. Sanders has released much less detail on M4A, by contrast. More importantly I don't see why you would focus on detail here. Most primary voters don't demand detail on most issues at this early stage, and candidates often win with minimal detail on some of their main proposals. Think about how light on detail Trump's wall proposal was, for example. Obviously the standard will be higher for a candidate marketing herself as "the candidate with a plan for that", but I think she's still gone above and beyond what most voters expect in this area.
What do you mean she's easily rattled? If the DNA test release is an example, fair. I haven't seen any further signs though.

Breaking:
New ABC/WaPo poll (national)
Biden 28 (-1%)
Elizabeth W. 23 (+5%)
Sanders 17 (-2%)
Buttigieg 9 (+5%)
....
Everyone else: 2% or less.
The last version of this poll was two months ago.
The topline is great for Buttigieg. He was already "top tier" in IA but now he's "top tier" nationally. Obviously a big gap still between him and the front-runner though.
