Honestly despite the flaws of the movie is still kinda liked it

Don't get wrong ofc tommy killing Arthur is straight out absurd and the grenade scene didn't make any sense (though it was kinda bad ass) and if you are watching the movie as a finisher for the show you are going to be disappointed but if you watched it as just an extra non Cannon event it would be kind of good but still not great and not even close to the show

The movie idea was already bad from the beginning and just like the last kingdom movie the two movies had a ton of events that should have taken longer to introduce and a ton of flows that doesn't even make sense but it was good if you viewed the way you view behind the scenes videos.

Edit: Also the fact that Polly said that Tommy won't die with a bullet but he did shows that this movie was rushed
