Let's start on a positive note...the fight scenes were brilliant, certainly the funniest parts of the movie. A bunch of drunks that can kill robots...not robots with action movie style and professional wrestling moves is almost too funny to watch.
Seeing Pegg and Black's characters interchanged was fresh as well, especially since Black pulls off the lovable Pub king and Pegg does a good job of looking like an old alcoholic.
And the last determined dash to hit the final two pubs was classic...
...but not of the same caliber as the previous two in the unofficial trilogy.
The alien thing was too...meh. Invasion of the Body Snatchers with an awkward Dreamcatcher vibe and it didn't work.
In fact, for the most part, a lot of it just took away from the humor as a whole. The build-up was a bit of a downer and by the time the comedy hit, the audience was gone.
The fun came too late in the film and for a long time it seemed like a drama with an amused grin and not the comedy that you'd expect.
This movie was divided into three parts for me. First there were the set-up scenes: Gary arranging the reunion tour and providing background of the five friends. It was fairly predictable and I found it almost impossible to overcome my dislike for the Gary character. It was only because I was slightly distracted by something else that I kept watching it. Then at about the 35-40 minute mark, it got better. There were action scenes, of course, but even the humor seemed to pick up the pace, and there was a little character development and growth. It was fun viewing for a long time.
Then there was the third section (again, for me anyway) when the plot is wrapped up at such an alarming speed so as to result in an anti-climax. And that is followed by a rather lackluster narration by one of the characters stating what had happened to everyone and explaining the ending that the movie had covered so scantly.
So I can’t say I regret watching it, but I probably wouldn’t watch it again if the opportunity arises.
