Finn Wolfhard is in a state of "shock" after he wrapped filming 'Stranger Things'

The actor - who starred on the show alongside the likes of Winona Ryder, David Harbour, Noah Schnapp and Millie Bobby Brown - wrote on Instagram: "We just wrapped Stranger things Season 5. I'm still in shock. We shot it for a year and I'll miss all of my friends and our characters terribly."

Finn observed that he's grown up alongside some of his co-stars. And the actor hopes that fans will love the fifth and final season of 'Stranger Things'.

He said: "I feel like we're still those people and I'm lucky to still stand beside them today. I hope you'll love this season as much as I do. See you all next year."

Meanwhile, David Harbour recently admitted that he can be "very critical" of 'Stranger Things'.

The 49-year-old actor has starred on the hit Netflix show since 2016, and David confessed to having some "very strong opinions" about the series.

Looking forward to the final season of 'Stranger Things', David said on the 'Happy Sad Confused' podcast: "I'm very close to the show, so I have very strong opinions. And they may not match yours if you're a fan of the show."

David admitted that he can actually get "very mad" if he doesn't like a particular episode.

The actor said: "I can be very critical of this show."

Despite this, David acknowledged that 'Stranger Things' is especially meaningful to the younger members of the cast.

He shared: "I think part of that also is the fact that these kids, it was their childhood.

"Like, they started the show when they were 11 and 12, and here we are reading [the finale]."
