Everything that the Buffy reboot has been doing wrong, Boom's MMPR series does right. Now that I have kids, I've been showing them a bit of the classics that I grew up with and, of course, Power Rangers is one of those classics. I actually read a few of these when they first came out, but life stopped me from getting too far into the series.
I'm glad that I am starting to read them again.
Volume One collects issues 0-4. This reboot sees the Rangers you grew up with (depending on how old you are at least) but with a more adult tone.
Remember that live-action film they did recently? Like that, but I'd say this is better (though I did like the film decently enough).
This collected volume is on ComiXology in their Unlimited selection, and is a pretty good start to the series. I'd recommend you to give it a shot if you've skipped out on it so far.
