The Westies arrives on MGM+ this weekend — you won't remember watching it in three months time, but this Irish mobster true story is fun while it lasts

If I'm going to watch yet another movie or TV show about a mafia-style gang in New York — because why bother in the wake of The Godfather and The Sopranos, right? — I want to come away from it having learned something new.

New MGM+ crime drama The Westies achieved this at conception, because I didn't know the first thing about the real-life Irish-American crime family of the same name. In fact, I didn't even know that they existed. But sure enough, they were known for racketeering, drug trafficking, and contract killing in Hell's Kitchen from 1960s-1980s.

I know what you're thinking: isn't Hell's Kitchen exactly where the Italian-American mob operated from in New York City. You'd be right in thinking that, and it's one of the main sources of dramatic tension across the show's eight-episode run.

Add in the fact that an FBI team has been tasked with tracking down our fictional version, led by family patriarch Eamonn Sweeney (J.K. Simmons), and you've got a proper old-school cat-and-mouse chase.

Interestingly, the biggest pro and con of The Westies is almost the same thing. While you're streaming it, you're engrossed — the storytelling itself is solid, dependable and superficially fun. But from the moment you switch it off, it will be completely erased from your mind.

Fans complained The Westies would be too tame just from the trailer — and I think they were right

After the above trailer for The Westies was released, I couldn't help but notice that the overwhelming fan response was to criticize scenes for being "too tame" compared to what mob behavior would have been like at the time.

Now that I've watched the entire season, I have to agree. Even if you don't know the story of the Westies, you're tuning into a gangster crime show expecting a severe level of violence — or even just an overarching sense of nasty brutality.

Of course, blood, guts and gore don't make a story any better objectively, but come on... we're trying to have some fun here. On top of that, it's difficult to invest in something new if you feel as though it is holding back, especially if it's aiming for a second season and beyond.

Still, the core storytelling is both engaging and well constructed. As Eamonn Sweeney's cronies face off against the local Italian-Americans, you're as engrossed in the inevitably fatal outcome as much as you are the complicated family dynamics.

The cast is stronger than its story

Bosch star Titus Welliver plays our ragged FBI lead Glenn Keenan, with an 80s "pornstache" so commanding that it might as well have had its own acting credit. When you can get past the facial accessories, you know you're in good hands... once Harry Bosch, always Harry Bosch, if you get what I mean.

If anything, I wish we had more of Simmons himself on screen. Sweeney isn't exactly the Don Corleone type, but it feels as though Simmons has somehow been a mobster boss in a former life. If you're selling him as number one on the call sheet, let's see that translated in each episode, please.

Really, I'm looking for holes when there aren't any — or at least I'm ripping tiny damaged flecks in the story's fabric into gaping tears. Because we've been so spoiled by shows such as Peaky Blinders and MobLand in recent years, we have to hold everything that comes after to an incredibly high standard.

Truthfully, The Westies just doesn't meet it. Not because there's anything wrong per se, but because the competition is so tough. It's kind of like studying really hard for an exam knowing you're going to get creamed by the kids who are naturally better at the same subject. Thems the breaks, so just enjoy the ride while it lasts.
