With some better acting and a sharper script this movie could have been a lot better than it was.What it is however is a fun romp through the trials and tribulations of time travel, poking good fun at its "rules" and issues. As well as classic Science Fiction in general. Sharp eyed views will see homages to "Them", "The Sound of Thunder", "Back to the Future", "Close Encounters", "Battlestar Galacticia" and others.Confined to a pub was a nice little bit as it kept all the action bottled up into one neat package and didn't require the exploration of the outside world.It's clever and fun.Now for the bad news. Well you have to admire the situation and the dry British humor (it was a BBC production after all)...the movie lacks any big laughs. Or even that many small ones. In better more comedic hands this could have been laugh out loud funny.Like I said it's clever and fun and should find an audience...but it's not "funny" and that's something a "comedy" should be.The question is...would I watch it again or pay money to see it? Yes, yes I would. I just think with a slight sharper edge to the humor and better actors this could have been so much more.

I enjoyed this movie, although I admit all the different time-travel threads had me a bit confused. Chris O'Dowd was charming as usual, and the other leads did well too. This is going to sound a bit nit- picky, but one thing that annoyed me was the British words that the American character kept using:1. An American is never going to call a closet a "cupboard", no matter how many times she's read Harry Potter. 2. She would also never say "quite dull" (she would say "really boring"). 3. We rarely ever, unless we're film critics, use the word "film" to mean a movie. 4. Also, although I love the word "sorted" as the Brits use it (it just has such a sense of finality and taken-care-of-ness to it), Americans never use it that way. If something is sorted, it means a bunch of papers or something that have been cataloged into different categories or piles or something - you know, SORTED.I just wish the producers had gotten an American to look over the American's dialog just once to weed out these distracting British- isms. Anyway, stupid points but they took me out of the world of the movie momentarily. Be sure to watch the entire credits - there's something right after them to see.

This is a fun, entertaining movie not to be taken to seriously. It was very entertaining. A comedic take on time travel. I ran across it on Amazon Prime and it had a four star rating so I thought I'd give it a shot. Three average guys are in a pub, one of who just got fired; they are SciFi buffs talking about time travel end up wrapped up in a time travel debacle. I would not call it hilarious but it was fun. It's in the same Genre as Galaxy Quest. A light hearted romp through the SciFi time travel zone.Anna Faris plays in it. We all know and love her from the Scary Movies. She plays a small part but important to the movie. I really liked the Giant ant they threw in.

Don't get turned off by the title. Even though the title sounds bit nerdy, the movie isn't a documentary or anything. It is a good time travel movie with humour and thrills. Most of us would have watched many time travel movies by now and hence are pretty familiar with the general rules in time travel movies. They are cleverly embedded in this movie too :) This movie gives me a hope that even I could time travel, without a machine or anything. Very enjoyable movie..keeps you really hooked. Wonder why it isn't more popular. I started watching at midnight with plans to hit bed soon..but i got so hooked that i ended up finishing it.
