As someone who used PowerShell for a year and has used Bash for 10+, PowerShell is much less scary than Bash. The scariest thing about PowerShell is .NET, which (at least 8 years ago or so, so cue someone correcting that below) had extensive but often low quality documentation, with undocumented features you basically had to use to write useful code, uselessly trivial code examples (think "`0 + 0 == 0`" as an example of arithmetic) and some bad names. That's not to say Bash is better, just that they still had some way to go.
