How I Met Your Mother Season 9, the final season of the hit CBS comedy, is fast approaching. It has yet to premiere, but 24 episodes will speed by in the next - and last - eight months of HIMYM. Cristin Milioti joins Ted Mosby (Josh Radnor) and his friends as the titular mother. Here are three reasons why she's perfect for the role.

How I Met Your Mother Season 9: 3 Reasons Cristin Milioti is the Perfect Future Mrs Mosby

When Cristin Milioti shows up for the first time in How I Met Your Mother Season 8 finale, the social media erupted with reactions from HIMYM fans. Some are thrilled; some are disappointed.

After eight years, the mother is finally revealed. It's exciting for many fans to know the mother will be introduced elaborately. Others had different expectations of how the mother should look like, and they were disappointed that How I Met Your Mother went another way.

Here are at least three reasons Cristin Milioti is likely to justify her HIMYM casting:

3. Half Lily, half Robin. Cristin Milioti has a lot of Alyson Hannigan's vibe as Lily Aldrin. And judging from her "30 Rock" guesting, Cristin can pull some Scherbatsky acts when the situation calls for it. She personifies the top two women closest to Ted Mosby. The guy couldn't be luckier.

2. Chemistry with Josh Radnor. Robin Scherbatsky (Cobie Smulders) and Ted Mosby still have some very hopeful fans. But this could change when Cristin's adorable dorky character is revealed. Neil Patrick Harris himself tells the HIMYM comic-con audience that Josh and Cristin have such strong chemistry together.

1. Cool, fun, smart acting. It takes a certain vibe and acting chops to play the role that's been described in various ways in a TV show's eight years. Cristin is up for the challenge, and she fits the mother's shoes well. Undaunted despite not being able to watch How I Met Your Mother in the past, Cristin is likely to impress viewers in the show's final season.

As a bonus, here's a video clip of Cristin Milioti performing some Irish music, Raglan Road from the poem of Patrick Kavanagh and music of Van Morrison. (Oh, how Ted Mosby will fall for this!)

In How I Met Your Mother Season 5, Ted Mosby's ex, Cindy (Rachel Bilson), speaks of the mother in a way Ted couldn't miss she is the perfect girl for him. But spoilers indicate all of Ted's friends will not like the mother - initially, at least. HIMYM spoilers revealed, too, that Lily will be the first to meet Cristin's character. And the first impression will not be good.

How I Met Your Mother Season 9 premieres with a 1-hour show on Sept. 23. "The Locket" will see Ted Mosby returning to Robin her Central Park-buried "something old." The entire HIMYM final season happens during the Scherbatsky-Stinson weekend wedding. Flash forwards and flashbacks are expected for each of the last 24 episodes.
