I can't say I was too impressed with this one. But like the other episodes from this season, this one had its moments. I got some laughs out of Moe getting pounded to a charming railroad song, Nelson's lamb fandom, and the seemingly-indestructible reporter guy.
Other than that, this was a clunker. The opening bored me and the B-plot with Bart, Lisa, and Larry the Lamb didn't do anything for me.
The trailer seems to try to at least ground it a bit. Sure, you see Asgard and battles there, but there's also him just kicking ass in regular clothes. That works for me. One of my gripes is the hammer. It looks..boring?
