Just finished watching the Konosuba movie. It was hilarious seeing Kazuma's sexual moves getting thwarted but he did get some nice alone time with the villain. The ending was also very heartwarming. I hope the anime returns with a season 3 one day.
Watch Fate/Zero first as it serves as a prequel to UBW, and then the Heavens Feel movie trilogy after finishing those unless you don't mind watching them out of order. That's typically the recommended viewing order, though.Fate stay/night: Unlimited Blade Works. Recommended (the franchise as a whole actually) by some friends on another forum, so I thought I'd give it a try.
