First off, let me say that I did rather enjoy this film.
Yes, it is a rather (read: VERY) far-fetched premise. And yes, it does have some massive plot holes mainly because it completely disregards the space-time continuum. But this film is not designed to have you focus on these things. It is only after viewing that you realise just how stupid the whole thing is and where all the problems with time-lines etc, etc lie. Yet, I still found myself wanting to see it again.
The main characters play their parts very well. All the actors must have known exactly what they were getting themselves into and they are all willing participants. I did especially enjoy Rob Corddry's part as a washed up, dead end, dead beat alcoholic. His character was the fulcrum for the majority of the humour, both situational and verbal. Craig Robinson bought the light-hearted humour, as well as some of the best punch lines of the film. John Cusack played the 'serious' dramatic/comedic role and Clark Duke has his moments while helping to aim the whole package toward a younger demographic. Even the secondary characters have their moments of comedy glory.
There are genuine laugh out loud moments spread pretty evenly throughout which are based on plot and character, not just gross-out humour. And although gross-out humour is present it sits well because the film doesn't rely on it alone to deliver the laughs.
Another thing I found very entertaining about this movie was that as the characters travelled back to the 80's it was almost as if the humour did too. I don't mean to say that things descended into a 'Porkie's Revisited' or anything like that, but there were definite elements of the 80's present in the way the humour and characters come across. Think back to scenes you remember off the top of your head from Back To The Future, Caddy Shack, Ferris Bueller's Day Off, hell - even Breakfast Club. Hot Tub Time Machine just seemed to capture some of that and revive it for today's audiences.
I would recommend HTTM to anyone with a sense of humour not wanting to think too deeply and wanting to be entertained for 90 minutes.
Like I said at the top of this review... There are plot holes. There is no recognition of the space-time continuum - actually, the future repercussions of the character's actions would have never worked out like they do. And, really, at no point does the film actually make sense.
BUT... I was still entertained. I still laughed. I still wanted to see where the characters went. I still find myself remembering lines from the film and smiling. And, even after all I've just written, I'd still watch it again.
Can't say more than that now, can I?
